Question

H2SO4 is a strong acid, but HSO4- is a weak acid. Account for the difference in strength of these two related species.

Answer 1

Answer:

because HSO4 dissociate more H+ ions in it's aqueous solution

Answer 2

Explanation:

H2SO4 is a strong acid. When it looses a hydrogen, it becomes HSO4-, and gains a negative charge.

HSO4- is the conjugate base of H2SO4 but it can still give its Hydrogen away, and thus it is a weak acid as well. It's weak because it doesn't part with its hydrogen as easily as H2SO4 did.
