Solubility & Ksp

How much dissolves

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Ksp: the equilibrium constant for a salt dissolving (solid left out).
• Common ions lower solubility.
• Q > Ksp → precipitate forms.

Steps

1. A solid in balance
2. How soluble is silver chloride?
3. The common-ion effect
4. Two ions for one
5. Will it precipitate?
