Catod(-)
K⁺
2H20 +2e⁻ ---> H2 +2OH⁻

We can also say, that
K⁺ +OH⁻ +H2 = KOH +H2
At the cathode KOH and H2(gas) are formed.

The cathode in the electrolysis of an aqueous solution KCl is K⁺

Electroysis is simply an electric current that is sent through a liquid or solution containing ions, causing chemical breakdown.

Generally, the equation for the Chemical reaction is mathematically given as

2H20 +2e⁻ ---> H2 +2OH⁻

Hence

K⁺ +OH⁻ +H2 = KOH +H2

In conclusion, a cathode where KOH and H2 are formed the cathode in the electrolysis is K⁺
