consider the following reaction,
`Na_(2)CO_(3) + 2HCl to 2NaCl + H_(2)O + CO_(2)`
Equivalent weight of `Na_(2)CO_(3)` is

A

`0.05M`

B

`0.5M`

C

`5M`

D

can not be calculated

Text Solution

Verified by Experts

The correct Answer is:
A
Let m.eqts of `Na_(2)CO_(3) = x`
Let m.eqts of `NaHCO_(3) = y`
Using Hph, `(1)/(2)x = 0.1 xx 10 = 1 :. x = 2 = 1` millimole
Molarity of `Na_(2)CO_(3) = (1)/(20) = 0.05M`
