Salts & Solubility by PhET

This simulation will allow students to add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. They can compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts and then relate the charges on ions to the number of ions in the formula of a salt.

Using the simulation, students will:

• Rank the solubility of different salts.
• Determine the ratio of anions and cations that create a neutral compound.
• Calculate the molarity of saturated solutions, and Ksp values.
