Answer 1

Answer #1

H2SO4 has Ka1 value large.

So, it will dissociate completely into

0.100 M H3O+ and 0.100 M HSO4-

HSO4- will further dissociate to give some [H3O+] and [SO42-]. It will not dissociate completely.

So, [SO42-] will be less than 0.100 M

So, ultimately:

[H3O+] > 0.100 M

[HSO4-] < 0.100 M

[SO42-] < 0.100 M

[H2SO4] close to 0

Answer: a
