Equilibria

Question 1

Define buffer solution.

Answer 1

A solution in which pH does not change significantly when small amount of acids and alkalis are added.

Question 2

Define solubility product.

Answer 2

The product of the concentrations of each ion in a saturated solution of a sparingly soluble salt at 298 K, raised to the power of their relative concentrations.

Question 3

Define the common ion effect.

Answer 3

The reduction in the solubility of a dissolved salt achieved by adding a solution of a compound which has an ion in common with the dissolved salt.

Question 4

Define partition coefficient.

Answer 4

Partition coefficient is the equilibrium constant that relates the concentration of a solute partitioned between two immiscible solvents at a particular temperature.

Question 5

Define conjugate acid-base pair.

Answer 5

A pair of molecules that differs by the presence of a H+ ion.
