Question

And who can find n factor of Na2Co3

Answer 1

N factor will be 2. For a salt it is calculated by the charge present on the electropositive cation here its sodium.

Answer 2

Given: $Na_2CO_3$

To find: We have to find the n factor.

Solution:

To determine or find the n factor of any compound we have to follow the following steps-

n factor of any compound is defined as its change in oxidation number.

$Na_2CO_3$ dissociates as-

$Na_2CO_3\rightarrow 2Na^++CO_3^{2-}$

$Na_2CO_3$ dissociates to give sodium ion and carbonate ion.

n factor=change in the oxidation number.

n factor=2-0

=2

Thus n factor will be 2.

n factor of $Na_2CO_3$ is 2.
