Question

What is the n factor of ${\mathrm{CO}}_2$?

Answer 1

n-factor:

• The n-factor of salts is defined as the number of moles of electrons lost/gained by $1$ mole of the salt.
• For acids, the n-factor is described as the number of ${\mathrm{H}}^{+}$ ions substituted by $1$ mole of acid in a reaction.
• For bases, n-factor is defined as the number of ${\mathrm{OH}}^{–}$ ions replaced by $1$ mole of the base in a reaction.

n factor of ${\mathrm{CO}}_2$:

• The n-factor of ${\mathrm{CO}}_2$ is $0$, as there is no replaceable ${\mathrm{H}}^{+}$as well as ${\mathrm{OH}}^{–}$ ions present.
• There is no change in the oxidation state of ${\mathrm{CO}}_2$, thus n-factor becomes nil.
