Purpose: The purpose of this lab was to determine the freezing point of pure water‚ the experimental van’t Hoff factor for a substance and the molar mass of an unknown solution. Reagents: 25mL deionized Water ¼ to ½ inches of rock salt 25mL Sodium Nitrate (NaNO3 ) 25mL unknown solution – handle unknown solution carefully Procedure: For part 1‚ the freezing point of deionized water was determined. An ice bath was prepared by filling a 600mL beaker ¾ full of ice and covered with ¼ to

Awesomov Entropy is a measure of the unavailable energy in a closed thermodynamic system that is also usually considered to be a measure of the system ’s disorder‚ that is a property of the system ’s state‚ and that varies directly with any reversible change in heat in the system and inversely with the temperature of the system (Webster). Entropy is a fundamental aspect of not only physics and its relation to thermodynamics‚ but also to biology and cognition (Ben-Naim). As it’s used in Isaac Asimov’s

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

Exp. 2A-D Solubility (pp.13-20) In this experiment‚ I will be determining/investigating the solubility of different solvents‚ or more precisely‚ the extent to which a substance is soluble or insoluble (Part A and B). Another goal of this experiment will be determining miscible (liquids that will mix homogeneously) and immiscible (liquids that do not mix homogeneously) parts in liquids (Part C). Part D of the experiment will be looking at solubility as well‚ the solubility of organic acids and
