Question

What is the special name given to the equilibrium constant for the dissolving of an ionic solute in water?

Short answer

The special name given to the equilibrium constant for the dissolving of an ionic solute in water is called the "Solubility Product Constant (Ksp)". It is used to predict the solubility of sparingly soluble salts and determine the degree of solubility of an ionic solute in water.

Step-by-step solution

Definition of Equilibrium Constant

An equilibrium constant (K) is a dimensionless value that expresses the ratio of the concentrations of the products to the concentrations of the reactants in a chemical reaction at equilibrium. It is expressed using the equilibrium concentrations of the species involved in the equilibrium expression, raised to the power of their stoichiometric coefficients.

Introduction to Solubility

Solubility refers to the maximum amount of solute that can dissolve in a solvent at a given temperature and pressure. When an ionic solute dissolves in water, it dissociates into its constituent ions. The equilibrium is established between the undissolved solute and the ions in solution.

Equilibrium Constant for the Dissolving of an Ionic Solute in Water

For the dissolving of an ionic solute in water, the equilibrium constant is called the "solubility product constant" and is represented by Ksp. The solubility product constant is a measure of how much of the ionic solute can dissolve in water at equilibrium.

Special Name for Equilibrium Constant for Dissolving of an Ionic Solute in Water

The special name given to the equilibrium constant for the dissolving of an ionic solute dissolved in water is called the "Solubility Product Constant (Ksp)". It is an important concept used to predict the solubility of sparingly soluble salts and helps in determining the degree of solubility of an ionic solute in water.
