0000001276 00000 n 0000008546 00000 n Experiment: Factors affecting solubility . 0000007293 00000 n Solubility refers to the ability of a given amount of a soluteto dissolve in a solvent. 4 0 obj For liquids and solids, solubility’s generally increase with increasing temperature, as is the case with sugar in tea. In addition, the change in solubility for a given salt, say between 20° and 30°C, may not be the same as the change in its solubility between 50° and 60°C. Once the solid is dissolved, the solution will be In this experiment, you will construct a solubility curve for KNO 3.

Use this experiment to determine if temperature has any effect on solubility. found that temperature effects on solubility vary from salt to salt. Method: Measure 100cm3 of water into a beaker ; Measure 100 g of salt and place into another beaker ; Slowly pour the salt into the beaker with the water, stirring it as you add. <> 0000006683 00000 n ]�%��m�94���7q��>��{���5��P�|��g��@��N�6�f%-+|_B�� Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. 0000002869 00000 n %PDF-1.5 0000001795 00000 n Most common chloride salts are soluble in water except silver chloride (AgCl), lead (II) chloride (PbCl 2).
