At cathode: H 2 O + e - arrow overset⊕ O H +(1/2) H 2 (one) At anode: 3 HCOO Θ arrow 2 CO 2+ H 2 (two) H 2 and CO 2 at anode and H 2 at cathode. So, number of gases as in 2(2)

Q. During the electrolysis of aqueous solution of $H COO K$ , the total number of gases obtained at cathode and anode is ______.

At cathode:
$H_{2} O + e^{-} \to O \oplus H + \frac{1}{2} H_{2}$ (one)
At anode:
$3 H CO O^{Θ} \to 2 C O_{2} + H_{2}$ (two)
$H_{2}$ and $C O_{2}$ at anode and $H_{2}$ at cathode.
So, number of gases as in $^{2} (2)$

Q. During the electrolysis of aqueous solution of HCOOK, the total number of gases obtained at cathode and anode is ______.

At cathode: H2​O+e−→O⊕H+21​H2​ (one) At anode: 3HCOOΘ→2CO2​+H2​ (two) H2​ and CO2​ at anode and H2​ at cathode. So, number of gases as in 2(2)
