10.1 Solutions. Dissolution of substances in water.

Salts & SolubilityAdd different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

10.2 SOLUBILITY OF SUBSTANCES. FACTORS AFFECTING SOLUBILITY

Sugar and Salt SolutionsWhat happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.
