Ksp Predictions

IQ4: How does solubility relate to chemical equilibrium?

Students:

● derive equilibrium expressions for saturated solutions in terms of Ksp and calculate the solubility of an ionic substance from its Ksp value

● predict the formation of a precipitate given the standard reference values for Ksp

22. Using Ksp

This presentation covers how to calculate Ksp and how to determine the likelihood of a precipitate.

You will need your HSC Data sheet for this lesson.

This worksheet contains a variety of Ksp problems and can be supplemented with your KISS Notes.
