Question

Which one is a polyprotic acid in aqueous solution?

A: Li(OH)2

B: HClO4

C: H2O2

D: H2SO4

Please explain "polyprotic acid"

Answer 1

Answer #1

Monoprotic acid is acid that gives only one H+

Polyprotic acid is the acid which has more than one ionisable H+

H2SO4 is polyprotic acid as it can donate 2 H+

H2SO4 —> 2H+ + SO42-

Answer: D

Answer 2
