Relating Solubility and Ksp - Saylor Academy

(A saturated solution is when there is a state of equilibrium between the dissolved dissociated undissolved solid and the ionic compound) For example let's take the compound Barium Carbonate BaCO3 (this is an ionic compound that is not very soluble) BaCO3(s) Ba2+ (aq)+CO32- (aq) First we can write down the equilibrium constant expression:

Solutions can be saturated unsaturated or supersaturated A saturated solution contains the maximum amount of solute that can dissolve The amount of solute needed to make a saturated solution depends on the identity of the solute the solvent and the temperature of the solution An unsaturated solution can dissolve more solute

What are some examples of saturated solutions?

Saturated solution examples range from familiar everyday solutions, such as carbonated drinks saturated with carbon dioxide, to natural examples, such as groundwaters saturated with calcium carbonate or silicon dioxide. Adding powder until it accumulates at the bottom of the glass (no longer dissolves) creates a saturated solution.

What are the steps for preparing a saturated solution?

There's more than one way to make a saturated solution. You can prepare it from scratch, saturate an unsaturated solution, or force a supersaturated solution to lose some solute. Add solute to a liquid until no more dissolves. Evaporate solvent from a solution until it becomes saturated.

What is the definition of a saturated solution?

A saturated solution contains more solute per volume of solvent than an unsaturated solution. The solute has dissolved until no more can, leaving undissolved matter in the solution. Usually, the undissolved material is denser than the solution and sinks to the bottom of the container.

What is the difference between saturated and unsaturated solutions?

A saturated solution is a solution in which no more solute can be dissolved and it contains the maximum amount of solute that can be dissolved. An example of saturated solutions is Carbonated water. A solution that contains a solute lesser than the maximum amount of solute that is capable of being dissolved is known as an unsaturated solution.
