Question

What is the $pH$ value of $M H _{2} SO _{4}$ ?

• A. 0
• B. -0.213
• C. -2
• D. -0.301

Answer 1

Answer: (D)

-0.301

Answer 2

The correct answer is Option is D) -0.301

$M H _{2} SO _{4} =2 N H _{2} SO _{4}$
$\left[ H ^{+}\right] =N \cdot \alpha$
$=2 \times 1=2$
$pH =-\log \left[ H ^{+}\right]$
$=-\log 2$
$=-0.3010$
