Question

The hydrogen ion concentration is a given solution is $6\times {10}^{-4}$ Its $pH$ will be:

• A. $6$
• B. $4$
• C. $3.22$
• D. $2$

Answer 1

The correct option is C $3.22$

Here answer is option C

$pH=-log\left[H_3{O}^{+}\right]given,\left[H_3{O}^{+}\right]=6\times 10^{-4}mol{L}^{-1}pH=-log[6\times 10^{-4}]\cong 3.22$
