Calculate the equivalent mass of `Na_(2)CO_(3)` when it is titrated against HCl in presence of phenolphthalein.

A

106

B

53

C

26.5

D

212

Text Solution

Verified by Experts

The correct Answer is:
A

The reaction involved is,
`Na_(2)CO_(3)+HCl to NaCl+NaHCO_(3)`
Equivalent mass of `Na_(2)CO_(3)=(106)/(1)=106`
