Calculating Molar Solubility and Common Ion Effects

The video tutorial explains how to calculate the solubility product constant (Ksp) for various compounds, including nickel carbonate, calcium hydroxide, calcium phosphate, barium phosphate, silver bromide, lead iodide, silver phosphate, and lead phosphate. It covers the use of molar solubility, chemical reactions, and equilibrium expressions. The tutorial also discusses the common ion effect on solubility, particularly for lead fluoride, and provides step-by-step calculations and explanations for each example.

What is the formula to calculate the Ksp value?

• Ksp = [Reactant]^coefficients

• Ksp = [Product] / [Reactant]

• Ksp = [Reactant] / [Product]

• Ksp = [Product]^coefficients

What is the Ksp expression for a reaction?

• [Products] / [Reactants]

• Products * Reactants

• [Reactants] / [Products]

• [Products]^coefficients

How do you calculate the concentration of hydroxide in calcium hydroxide solution?

• Multiply molar solubility by 2

• Divide molar solubility by 2

• Square the molar solubility

• Take the square root of the molar solubility

What is the molar solubility of calcium hydroxide?

• 6.875 x 10^-3 M

• 1.3 x 10^-6 M

• 3.74 x 10^-4 M

What is the Ksp value for calcium phosphate?

• 1.3 x 10^-32

• 6 x 10^-39

• 1.4 x 10^-7

• 1.3 x 10^-6

What is the role of coefficients in the Ksp expression?

• They become subscripts

• They are added to the Ksp value

• They turn into exponents

• They are ignored

What is the molar solubility of silver bromide (AgBr)?

• 1.607 x 10^-5 M

• 6.21 x 10^-12 M

How does the common ion effect influence the solubility of a salt?

• Only affects gases

• Increases the solubility

• Decreases the solubility

• Has no effect on solubility
