The market value of propionic acid as a feed acidifier was the highest in 2012‚ and is projected to grow with the increasing demand for feed acidifiers in the livestock industry. The benefits of feed acidifiers are leading the market demand in the feed industry. The fumaric acid market is comparatively small and is projected to grow at a CAGR of 5.8% from 2013 to 2018. The feed acidifiers market is projected

Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1.20g was added immediately afterwards

Acid Property #1: The word acid comes from the Latin word acere‚ which means "sour." All acids taste sour. Well known from ancient times were vinegar‚ sour milk and lemon juice. Aspirin (scientific name: acetylsalicylic acid) tastes sour if you don’t swallow it fast enough. Other languages derive their word for acid from the meaning of sour. So‚ in France‚ we have acide. In Germany‚ we have säure from saure and in Russia‚ kislota from kisly. Base Property #1: The word "base" has a more complex

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere
