Answer 1

Answer:

Hydrogen, Oxygen

Explanation:

Acidulated water is water where some sort of acid is added.

Ionization of acidified water:

$H_{2}O -------H^{+} + OH^{-}$H  

$H_{2}SO_{4} ------- 2H^{+} +SO_{4} ^{2-}$

 

Ions present in solution are $SO_{4} ^{2-}$, $H^{+} and OH^{-}$  

+ve charge move towards cathode whereas -ve charge move towards anode.

Reaction at cathode:

$H^{+} + e^{-} -----------H\\H + H-----------H_{2}$

Reaction at anode

$OH^{-}$  ion discharge in preference to $SO_{4} ^{2-}​$

$OH^{-} ------------ OH + e^{-}\\4OH --------------2H_{2}O + O_{2}$

Hence, during electrolysis of acidulated water, hydrogen is collected at cathode and oxygen is collected at anode.
