Write the formula and name of the conjugate base for each of the following acids:

a. HCN(aq)

b. NH4+(aq)

c. H2CO3(aq)

d. HSO4-(aq)

e. HClO2(aq)

Write the formula and name of the conjugate acid for each of the following bases:

a. CO32-(aq)

b. SH-(aq)

c. H2PO3-(aq)

d. Br-(aq)

e. NO2-(aq)

What are the major species present in 1.0 M solutions of the following:

a. hydrosulfuric acidb. perchloric acid

c. permanganic acidd. hydroiodic acide. sodium chloride

Percent dissociation can be used to calculate Ka!

Predict whether an aqueous solutions of the following salts will be acidic, basic or neutral:

NH4C2H3O2Ka for NH4

+ = 5.6 x 10-10, Kb for C2H3O2- = 5.6 x 10-10

NH4CNKa for NH4

+ = 5.6 x 10-10, Ka for HCN = 6.3 x 10-10

Al2(SO4)3Ka for Al(H2O)6

3+ = 1.4 x 10-5, Ka2 for H2SO4 = 1.2 x 10-2
