Four acids `HA,HB,HC` and `HD` form salts with `NaOH` of `Ph` 7,8,9 and 10 respectively when each solution was `0.1M`, the strongest acid is `:`

A

`HA`

B

`HB`

C

`HC`

D

`HD`

Text Solution

Verified by Experts

The correct Answer is:
1
`{:("Salts",,pH),(NaA,,7),(NaB,,8),(NaC,,9),(NaD,,10):}`
`A^(-)` is the weakest conjugate base. Hence, HA will be strongest acid
