Question

Select the $p{K}_a$ value of the strongest acid from the following.

• A. $1.0$
• B. $3.0$
• C. $2.0$
• D. $4.5$

Answer 1

The correct option is A $1.0$

$p{K}_a$ known as acid dissociation constant which define the acidic strength of any acid. Higher the $p{K}_a$ value weaker the acid.

Thus, $p{K}_a=1$ will be strongest acid among all

option A
