Chapter 16: Acid-Base Equilibria and Solubility Equilibria

Question 1

Buffer Solution

Answer 1

The solution of (a) a weak acid or base and (b) its salt; both components must be present. The solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base.

Question 2

Common ion effect

Answer 2

The shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substances

Question 3

Complex ion

Answer 3

An ion containing a central metal cation bonded to one or more molecules or ions

Question 4

End point

Answer 4

The pH at which the indicator changes color.

Question 5

Formation constant (K_f)

Answer 5

The equilibrium constant for the complex ion formation

Question 6

Molar solubility

Answer 6

The number of moles of solute in one liter of a saturated solution (mol/L).

Question 7

Qualitative analysis

Answer 7

The determination of the types of ions present in a solution.

Question 8

Solubility

Answer 8

The maximum amount of solute that can be dissolved in a given quantity of solvent at a specific temperature.

Question 9

Solubility Product (K_sp)

Answer 9

The product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.
