Solubility Equilibria and Poison Management

These flashcards cover key terms and definitions related to solubility equilibria and the concepts associated with toxins in food and water.

Equilibrium Constant (K)

A numerical value that represents the ratio of the concentration of the products to the concentration of the reactants at equilibrium.

Solubility Product Constant (Ksp)

The equilibrium constant for the solubility of a sparingly soluble ionic compound expressed as the product of the concentrations of its ions.

Le Chatelier's Principle

If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

Common Ion Effect

The reduction in solubility of an ionic compound when a common ion is added to the solution.

Saturated Solution

A solution that has reached the maximum concentration of solute that can be dissolved at a given temperature and pressure.

Dissolution Equilibrium

The state in which the rate of dissolution of a solid into a solution equals the rate of precipitation of that solid from the solution.

Molarity (M)

A measure of concentration representing the number of moles of solute per liter of solution.

Concentration Quota (Q)

The ratio of the concentrations of products to reactants at a given time, which can help predict the direction of the shift in equilibrium.

Equilibrium Shift

The change in the concentrations of reactants and products to reach a new equilibrium state when disturbed.

Solubility Limit

The maximum concentration of a solute that can dissolve in a solvent at a given temperature and pressure.
