Thermodynamics of Borax C3C Justin Nevins Chemistry 200‚ Section M1A Introduction The purpose of the lab was to determine how the solubility of Borax (Na2B4(OH)4) and other thermodynamic quantities such as enthalpy‚ entropy‚ and Gibbs free energy depend on temperature. When Sodium borate octahydrate (Borax) dissociates in water it forms two sodium ions‚ one borate ion and eight water molecules. The chemical reaction is shown as: (reaction 1) A simple acid-base titration

Heats Effect on Borax By: Alexis H. Prince Department of Chemistry; Coastal Carolina University‚ Conway‚ SC 29526 April 13‚ 2015 Introduction Borax has many uses‚ whether it’s being used as an antiseptic‚ helping to cure people‚ getting rid of pests‚ or even assisting fruit trees in their growth. It is actually the most important source of the element boron‚ and has been used for years as a “water softening agent.” Borax was found forming in saline lakes‚ or one may find it in Boron‚ California

said to be in thermal equilibrium and to be equal in temperature. The 2 systems are equal in temperature when no change in any property occurs when they are brought into communication. 5.2 The Zeroth Law of Thermodynamics (This law was formulated after the First Law of Thermodynamics. Since it is more fundamental‚ it is called the Zeroth Law) It was observed experimentally that 2 systems that are equal in temperature to a third system are also equal in temperature to each other. This may

Thermodynamics Lab Introduction: Thermodynamics is the study of energy which can exist in many forms‚ such as heat‚ light‚ chemical energy‚ and electrical energy. The variables that thermodynamics can be used to define include temperature‚ internal energy‚ entropy‚ and pressure. Temperature‚ relating to thermodynamics‚ is the measure of kinetic energy in the particles of a substance. Light is usually linked to absorbance and emission in thermodynamics while pressure‚ linked with volume‚ can do
