<h3>What is a word equation?</h3>A word equation represents a chemical reaction using the names of the substances involved.
a) Word equation:
Sodium chloride + electrolysis → Sodium hydroxide + Hydrogen gas, Chlorine gas
b) The following reactions take place during the electrolysis of brine solution :
NaCl =
=
Now there are two cations and two anions which get discharged in the following way :
At cathode : =
At anode: =
The remaining ions
= NaOH
That's why we get ,
and NaOH.
c) Balance each equation is:
2NaCl (l) → 2Na(s) + (g)
