Answer #1

a.

H2SO4 is a diprotic acid it dissociate as sown below H2SO4 (aq) -------> HSO4- (aq) + H+ (aq) (The First dissociation is 100%b.

Kb indicates base dissociation constant

the Kb equation for HSO4- can be shown as

HSO4- (aq) + H2O (l) < ----- > H2SO4 (aq) + OH- (aq)

this is the reversal of Ka1 reaction ,

so , Kb = Kw / Ka1 , where Kw = 1.0*10^-14 , Ka1 = 1000

so Kb = 1.0 * 10^-14 / 1000 = 1.0 * 10^-17

c.

During the dissociation of KHSO4 in water it produces H+ ions .

so it must be acid

HSO4- (aq) + H2O (l) < ----- > SO4 2- (aq) + H3O+ (aq) , Ka2 = 0.01023

here Kb is <<< Ka2 so , KHSO4- is a acidic
