FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

Use solubility of group 2 to figure out periodic trends as well as identify unknown captions Introduction The goals of this experiment were to determine periodic trends in solubility of group 2 metals. The other goal was to use our knowledge of solubility’s to identify cations present in a single unknown Xe and double unknown XXe. I have hypothesized that the solubility

Abstract The aim of this experiment is to determine the relationship between the solubility of potassium hydrogen tartrate (KHC4H4O6) and temperature. Titrate a known concentration of NaOH against a saturated solution of KHC4H4O6 at different temperatures to obtain the concentrations

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
