d. CO^23 −(aq)+H 2 O(l)⇀↽HCO− 3 (aq)+OH−(aq)- Referring to question 6, identify the conjugate acid-base pairs in each reaction.
- Write the formula of each acid’s conjugate base.
a. HNO 3
b. HSO 3 −
c. H 3 AsO 4
d. HCOOH - Write the formula of each base’s conjugate acid.
a. BrO 3 −
b. NH 3
c. CH 3 COO−
d. HCO 3 − - Explain why the hydrogen phosphate ion (HPO 42 −) is amphoteric.
- A positive cation, such as Al^3 +, undergoes a Lewis acid-base reaction with water. Explain, and identify which
species is the Lewis acid and which is the Lewis base.

Points to Consider
The relative acidity or basicity of an aqueous solution is measured using a scale called the pH scale.
- How are the hydrogen and hydroxide ion concentrations related in all aqueous solutions?
- How is the pH of a solution calculated?
