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
Correct Answer: Option 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).
