Answer #1

clearly it is given arginine formula H3A2+

H3A2+ + H2O < ----------------------> H2A+ + H3O+ , Ka1

H2A+ + H2O <-----------------------> HA + H3O+ , Ka2

HA + H2O <--------------------> A- + H3O+ , Ka3

for Kb

Kb1 = Kw / Ka3

Kb2 = Kw / Ka2

Kb3 = Kw / Ka1

so for Kb1

A- + H2O -------------------> HA + OH-

now coming to our question and answers

A) for Kb1

A- + H2O <-------------------> HA + OH-

B) for Ka2

H2A+ + H2O <-----------------------> HA + H3O+
