In this lesson, we will learn how to explain and calculate the solubility product.

Students will be able to

Q1:

The smaller the solubility product of a substance, the lower its solubility.

Which of the following statements is true when the product of the ion concentration is equal to the solubility product?

Which of the following statements is true when the product of the ion concentration is greater than the solubility product?

Which of the following statements is true when the product of the ion concentration is less than the solubility product?

Q2:

What is the equation for the solubility product of a generic inorganic compound with the formula MA?

Q3:

A saturated solution of copper(II) hydroxide (Cu(OH))2 contains 1.72×10 g of Cu(OH)2 in every 1 dm^{3} (1 L) of water.

Taking the molar mass of Cu(OH)2 to be 97.56 g/mol, what is the value of 𝐾sp without units, to two decimal places in scientific notation?

What is the unit of 𝐾sp for this hydroxide?
