# Write an expression for ksp for the dissolution of caco3 molar

Example 5 Determination of Ksp from Gram Solubility Many of the pigments used by artists in oil-based paints Figure 2 are sparingly soluble in water. Solution The solubility product constant of calcium hydroxide is 1. Oil paints contain pigments that are very slightly soluble in water. When the solubility of a compound is given in some unit other than moles per liter, we must convert the solubility into moles per liter i.

## Write an expression for ksp for the dissolution of caco3 molar

Solution: A The only slightly soluble salt that can be formed when these two solutions are mixed is BaSO4 because NaCl is highly soluble. Solution First, write out the Ksp expression, then substitute in concentrations and solve for Ksp: A saturated solution is a solution at equilibrium with the solid. Whereas solubility is usually expressed in terms of mass of solute per mL of solvent, Ksp is defined in terms of the molar concentrations of the component ions. B To find the mass of solute in mL of solution, we assume that the density of this dilute solution is the same as the density of water because of the low solubility of the salt, so that mL of water gives mL of solution. The solution is unsaturated, and more of the ionic solid, if available, will dissolve. The pathway of the sparingly soluble salt can be easily monitored by x-rays. Calculate the molar solubility of silver iodide. Answer: 1. Figure 2. More important, the ion product tells chemists whether a precipitate will form when solutions of two soluble salts are mixed. Solution The solubility product constant of calcium hydroxide is 1. What is the solubility product of fluorite? Oil paints contain pigments that are very slightly soluble in water. The equilibrium constant for a dissolution reaction, called the solubility product Ksp , is a measure of the solubility of a compound.

The ion product Q is analogous to the reaction quotient Q for gaseous equilibria. Solution: A The only slightly soluble salt that can be formed when these two solutions are mixed is BaSO4 because NaCl is highly soluble.

## Identify the correct expression for ksp for the dissolution of caco3.

Determine the solubility product equilibrium constant for PbCrO4. Calculate the molar solubility of silver iodide. Oil paints contain pigments that are very slightly soluble in water. B To find the mass of solute in mL of solution, we assume that the density of this dilute solution is the same as the density of water because of the low solubility of the salt, so that mL of water gives mL of solution. Figure 2. Solution First, write out the Ksp expression, then substitute in concentrations and solve for Ksp: A saturated solution is a solution at equilibrium with the solid. The solution is unsaturated, and more of the ionic solid, if available, will dissolve. Example 2 Calculation of Ksp from Equilibrium Concentrations We began the chapter with an informal discussion of how the mineral fluorite Introduction to Chapter 15 is formed.

More important, the ion product tells chemists whether a precipitate will form when solutions of two soluble salts are mixed. Whereas Ksp describes equilibrium concentrations, the ion product describes concentrations that are not necessarily equilibrium concentrations.

What is its solubility product? Ksp and Solubility Recall that the definition of solubility is the maximum possible concentration of a solute in a solution at a given temperature and pressure.
