Question 1

Order the following acids in order of increasing strength:

HBrOHBrO3HBrO4HBrO2

◦ HBrO2 < HBrO4 < HBrO < HBrO2
◦ HBrO < HBrO2 < HBrO3 < HBrO4
◦ HBrO4 < HBrO3 < HBrO2 < HBrO
◦ HBrO < HBrO3 < HBrO4 < HBrO2
◦ HBrO < HBrO3 < HBrO2 < HBrO4

Question 2

Determine the concentration of CO32- ions in a 0.18 mol L-1 H2CO3 solution. Carbonic acid is a diprotic acid with Ka1 = 4.3 × 10-7 and Ka2 = 5.6 × 10-11.
◦ 4.3 × 10-7 mol L-1
