Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent‚ heat is absorbed. The reaction is endothermic. In this case‚ an increase in temperature increases solubility. For some substances‚ heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case‚ an increase in temperature

The data collected supported the hypothesis and the tablets were significantly more dissolved than the gelcaps and caplets. This experiment could be changed by having a component stir the acetaminophen and the water together. Introduction The solubility of medicine is important because the quicker it dissolves‚ the quicker is can start working. There are many different forms of Acetaminophen on the market. This experiment is an attempt to discover which form of Acetaminophen will dissolve the quickest

Preliminary Test and Solubility Classification of Organic Compound Keene Louise Topacio‚ Christopher Jay Robidillo Abstract The experiment focuses on how to classify organic compounds by its functional groups. It is done by preliminary test and with the solubility test. Preliminary test used two known compounds also the unknowns. Physical state‚ color‚ odor‚ and ignition test were noted. The known compounds are inorganic and organic compounds. A comparison is made from the observation in the unknown

HOW DOES THE SOLUBILITY OF POTASSIUM CHLORIDE (KCL) AND POTASSIUM IODIDE (KI) IN WATER VARY WITH TEMPERATURE? AIM To observe solubilities of KCl and KI with water at different temperatures To compare the two solubility curves and discuss what might vary the solubility of different ionic compounds. THE VARIABLES DEPENDENT VARIABLE Temperature INDEPENDENT VARIABLE Amount of solute (KCl‚ KI) CONSTANTS Amount of the solvent (water)‚ pressure APPARATUS 100G OF POTASSIUM CHLORIDE 100G

The Solubility of Potassium Nitrate Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated‚ and if yes‚ by how much. Hypothesis: According to data on the internet‚ 3.75 × 10¹ moles of potassium nitrate dissolve in 100g of water. I believe this information may be correct. I also believe that as the solute is absorbing outside heat‚ the energy is increased causing it to dissolve both faster‚ with
