A sample of `Na_2CO_3H_2O` weighing 0.62 g is added to 100 mL of 0.1 N `H_2SO_4`. Will the resulting solution be acidic, basic or neutral ?

A

acidic

B

neutral

C

alkaline

D

strongly alkaline

Text Solution

Verified by Experts

The correct Answer is:
B
Gram equivalents of `Na_(2)CO_(3).H_(2)O = ("mass")/("Eq. mass") = 0.62/62 = 0.01`
Gram equivalents of `H_(2)SO_(4) = (N xx V)/1000 = (0.1 xx 100)/1000 = 0.01`
Since, the gram equivalents of the two are equal, the resulting solution would be neutral.
