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

can also be dissolved in a liquid solution. c. Solid Solution- is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature. 3. Solubility is the ability of one compound to dissolve in another compound. 4. a. Temperature - Basically‚ solubility increases with temperature. It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in

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

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
