Lab#3 Separation of a Mixture of Solids
Title:
Lab #3 Separation of a Mixture of Solids
Purpose:
To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment, I will separate a mixture of four distinct substances: sodium chloride, benzoic acid, silicon dioxide, and iron fillings into pure beings.
Procedure:
Materials:

distilled water coffee cups (2) plastic wrap sheet of paper(2) small saucer paper towels crushed ice
100mL beaker, glass
Burner – fuel
Burner-stand
Cylinder, 25mL
Funnel
Goggles
Digital scale
Magnet bar
Stirring rod
Filter paper
Mixture of solids(salt, sand, benzoic acid, iron fillings)
Plastic weighing boat

Procedure:
1. Separating out the Iron – this method uses irons property of being magnetic to single it out from the other substances which do not respond to a magnet.
a) Use scale to find the mass of your weighing boat. Then pour the mixture of solids into the boat and weigh it again. Then find the net mass of the mixture by taking the weight of the weighing boat and mixture and subtracting the mass of just the weighing boat.
b) Spread mixture into a thin layer on a sheet of paper. Cut the second piece of paper into a 10-cm square, weigh and record its mass.
c) Cut the plastic into a small square t fit around the magnet. Wrap plastic over the magnet. Then pass magnet closely over the surface of the mixture. Repeat several times, and then hold magnet over the square of paper, carefully remove plastic to let iron fall to the paper. Weigh it and determine the net mass of the iron fillings.
2. Separating out the Sand – this method involves dissolving all soluble remaining substances so the only thing left is sand since it does not dissolve into water.
a) Put the remaining mixture into the beaker and 50mL of water. Set up beaker stand and fuel, and heat beaker

    At first the technique of filtration to filter the sand from the salt water is used. Filtration is a procedure that separates a heterogenous mixture, with the use of filtration paper. Then the mass of the sand will be found using a balance. A balance is an instrument that finds the mass of an object. Evaporation is then used to separate the homogenous salt water mixture. The salt will be separated from the water through evaporation. Evaporation is a separating technique that uses some form of heat to evaporate a liquid leaving behind any substance not chemically bonded to the H2O. Also, an oven will be used to get rid of leftover moisture in the sand.…

    Separation of Mixture of Solids

    In the beginning of the lab, I thought that in order to separate all of the solids that the iron would be taken out of the mixture through a magnet. I would first, placed the mixture of solids onto a piece of paper. The magnet’s force would pick up all the iron pieces. Continuing on, in order to separate the sand from the rest of the mixture I would heat the mixture with water in a beaker then would continue by pouring the heated liquid into a cup, which would leave sand at the bottom of the beaker. Lastly, to separate the benzoic acid and sodium chloride I would use a filtration system with the water drained into a cup while the benzoic acid remained on the filter, letting the sodium chloride drain with the water. I would then wait for the rest of the water to evaporate from the cup in order to obtain the weight of the sodium chloride.…

    Separating A Mixture Experiment

    For this procedure in this experiment it consisted of different processes to separate a mixture of solids into the four individual solids: sand, Table Salt, iron fillings, and Raisens. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the iron pieces. Then to separate the sand from the rest of the mixture I heated the mixture with water in a beaker and when I poured the heated liquid into a cup the sand remained in the bottom of the beaker. Lastly to separate the Raisens and Table Salt, I used a filtration system and the Table Salt and water drained into a cup while the Raisens remained on the filter.…

    The Physical Process of Separating Australian Industrial Mixtures

    Iron (FE) is a metallic element which makes up roughly 5% of the earth’s crust. Iron is mined vastly throughout Australia in many different areas including Tasmania, South Australia, Western Australia and Victoria. Australia is one of the world’s major iron ore producers, producing 393.9 Mt in 2009 alone, valued at roughly $30 billion. Iron serves many different purposes but it main use is to produce steel, steel is known to be the most useful metal being used 20 times more than any other metals found in the earth’s crust, therefore making the demand for fine quality iron ore extremely high. Iron ore is any form of rock in which iron can be economically extracted from. The iron within the rock comes in two main forms of iron oxides: magnetite and hematite. The three primary sources iron ores found within the earth’s crust are banded iron formations, magmatic magnetite ore deposits and hematite ore. The hematite and magnetite is physically extracted from the iron ore by using a fairly straightforward process of coarse crushing, fine crushing, classification, dry magnetic separating, floatation, thickening then drying. This process is known as dry magnetic separation.…

    Separation Challenge: Salt, Sand, Wood Chips, Iron Filings

    Final Plan: To separate sand, salt, wood chips and iron filings First, use a magnet to remove the iron. Since some sand/salt will get caught with the iron filings, you may have to spread out the separated iron filings on cardboard and do a second and even a third separation to get just iron. The sand, salt and wood chips that were trapped with the iron can be added back to the to the original mixture. To separate out the salt, add boiling water…

    Separation of a Mixture of Solids

    I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came to the conclusions that the salt would need hot water to separate from the mixture, the benzoic acid would need cold water to separate, the sand would settle on its own, and the iron filings could be separated with a magnet. My flow sheet was pretty accurate. We started by separating the iron, which was by far the coolest part, watching the magnet pull up every tiny filing of iron out of the mixture was awesome. Getting that iron onto the scale and off of the magnet was the hard part though. I removed the plastic, which I had wrapped around the magnet, but when I removed the plastic the iron filings simply left the plastic and continued to cling to the magnet, so I had to scrape them off and onto the scale by hand. Separating the sand was also pretty straightforward, we boiled the mixture in water in the beaker and the sand settled on its own. We poured out the solution into a paper cup, leaving the sand in the beaker. We attempted to heat the sand slowly to dry it out, but there was one big splatter that occurred and we lost a tiny bit of sand, but we then scrapped the sand out of the beaker and onto the scale to weigh it as best we could. Then adding the paper cup solution to a cup of ice water we watched as the benzoic acid crystalized and floated to the top. We then poured that solution through a filter and funnel into another cup, only allowing the saltwater solution to pass through the filter. The filter was left with a small, shiny, silver substance stuck to it…

    Separation Of Mixtures Lab Report

    The data in this experiment shows what you did to separate the mixture and if it was successful. The method of using magnetism to separate ion was successful. Separating the wood chip shavings from the salt and sand worked somewhat. There was still some sand particles mixed with the wood chip shavings in which you would use the forceps to separate the sand particles out. Mixing the salt and sand with water and placing it in filter paper was also successful. Finally, the boiling of the salt water and evaporating the water in which the salt was left was successful.…
