TITLE: Solubility and Thermodynamics PURPOSE: The purpose of the lab was to determine the thermodynamics variables of ∆H‚ ∆S‚ and ∆G for the dissolution reaction of potassium nitrate in water. The solubility of potassium nitrate in mol/L was measured over a range of various temperatures by finding out at what temperature crystallization began for solutions of different molarities. Then‚ the equilibrium constant was calculated and a graphical relationship between the natural logarithm of the

Bond By INSTRUCTOR: PURPOSE/INTRODUCTION The purpose of this experiment is to examine the properties of six common chemicals based upon their inherent molecular properties. Though this experiment‚ we can study and compare the bond properties of these chemicals. This experiment is also an introduction comparison of ionic and covalent bonding through real world testing. The properties of each type of bond will be exploited to the fullest during these tests. MATERIALS Materials required

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

All of my iodine reactions should have been soluble‚ my exception was Sodium Iodide and Copper(II) Nitrate. My barium Nitrate combined with Sodium sulfate was insoluble with is correct accourding to the solubility rules. All reactions with Chloride should have been soluble and they were. All Bicarbonate were in soluble‚ these I thought were soluble

developed primarily in the context of immediate release (IR) solid oral dosage forms. It is the scientific framework for classifying drug substances based on their aqueous solubility and intestinal permeability. It is a drug development tool that allows estimation of the contributions of three major factors‚ dissolution‚ solubility and intestinal permeability that affect oral drug absorption from immediate release solid oral dosage forms. The interest in this classification system is largely because

KF 1(a) SOLUBILITY OF AN SALT BY TITRATION Date : __________________________ Name : _____________________________________________________ Matric no. : __________________________ 1. Objective(s) of Experiment To measure the change in solubility product of potassium periodate (KIO4)‚ when an inert salt (NaNO3) is added to the solution. 2. Why important to determine solubility? The solubility product expression can be used for predicting whether or not precipitation will occur

didn’t have any reaction with other solution like B and D beside A‚ so if we look at the solubility chart‚ SO2- have only one precipitation with Ba2-. So we come to conclusion that C is CuSO4 and A is Ba(NO3)2 _ So now that we know C is CuSO4‚ other blue solution must be CuCl2 which is D‚ so according to chemical reaction experiment‚ D didn’t have any reaction with other solution beside B‚ if we look at solubility chart CuCl3 only have one precipitation with AgNO3. So we come to conclusion that B is

Principle predicts that the system would shift towards the product’s side in order to alleviate this stress. By shifting towards the product’s side‚ more of the solid is dissociated when equilibrium is again established - which equates to increased solubility. Second‚ imagine an exothermic reaction (heat is on the products side where the dissociated ions from the solid are). Increasing the temperature would result in stress on the products side from the additional heat. Le Châtelier’s Principle predicts

familiar with dissolution and precipitation equilibria‚ develop a lab technique suitable for the determination of the solubility for a sparingly soluble salt‚ Ba(NO3)2 (s) at room temperature and measure the common ion effect in solubility of Ba(NO3)2 (s) in an acidic solution‚ HNO3 (aq). Procedure: In this lab‚ the evaporation technique was used to determine the solubility of the salt at room temperature in water. First a 250ml beaker was weighed and the mass was recorded. Then 5.0g of barium
