20 cm3 of 1 M H $_2$ SO $_4$ is mixed 20 cm $^3$ of 1 M NaOH. The resulting solution is?

A.

acidic with a molarity of 0.50 M H₂SO₄

B.

acidic with a molarity of 0.25 H₂SO₄

C.

neutral

D.

alkaline with a molarity of 0.25 M NaOH

E.

alkaline with a molarity of 0.50 M NaOH

View answer & explanation

Correct answer is A

The balanced equation for the reaction is:

$2NaOH + H_2 SO_4 \to Na_2 SO_4 + 2H_2 O$

$\therefore 1M H_2 SO_4 \to 2M NaOH$

$1M NaOH \to 0.5M H_2 SO_4$

The resulting solution is Acidic with 0.5M H $_2$ SO $_4$ .
