Question

Explain electrolysis of acidulated water dilute H2So4

Answer 1

Acidulated water with $H_{2}SO_{4}$

Have the following ions

• Cations

$H^{+}$ only as wter release H + also h2so4 also releases H+

• Anions

1. $OH^{-} \:and\: SO_{4}^{-2}$

From electrochemical series of Metals and Of non metals

we get to know that OH- gonna oxidize

and hence

At Cathode

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

At Anode

$4 OH^{-}--------------------1 O_{2}+4e^{-}$
