20 cm3 of 1 M H\(_2\)SO\(_4\) is mixed 20 cm\(^3\) of 1 M NaOH. The resulting solution is?
-
acidic with a molarity of 0.50 M H2SO4
- acidic with a molarity of 0.25 H2SO4
- neutral
- alkaline with a molarity of 0.25 M NaOH
- alkaline with a molarity of 0.50 M NaOH
The correct answer is: A
Explanation
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\(_4\).
