The total number of diprotic acids among...

The total number of diprotic acids among the following is
`H_(3)PO_(4), H_(2)SO_(4), H_(3)PO_(3)`
`H_(2)CO_(3), H_(2)S_(2)O_(7), H_(3)BO_(3)`
`H_(3)PO_(2), H_(2)CrO_(4), H_(2)SO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
6
Diprotic acids have two ionizable hydrogen atoms. For example, `H_(2)SO_(4), H_(3)PO_(3) , H_(2)CO_(3), H_(2)S_(2)O_(7), H_(2)CrO_(4) and H_(2)SO_(3)`. Hence 6 acids are diprotic.
