Question

a highly concentrated solution of potassium sulphate in water is electrolysed using inert electrodes . the product at the cathode and anode are respectively

Answer 1

Potassium is liberated at the cathode and oxygen is liberated at the anode by the electrolysis reaction.

Explanation:

• Electrolysis is the process of breakdown of a substance into two or more substances. Here potassium is most likely to be deposited at the cathode because it is more reactive as compared to that of  hydrogen.

• On the other hand oxygen has more likely to get deposited as compared to sulfate. There is a gradual in increase in the acidity of the electrolyte due to the deposition of sulfuric acid

Answer 2

Answer:-

i will tell only about cathode (not sure about anode)

ans is hydrogen gas

Explanation:

bcoz from k+ and h+ the latter has greater reduction potential than k+ bcoz in electrochemical series we tak that elemamt at cathode shich js lower in series

and hydrogen is lower than potassium

And for anode sulphate ion goes bcoz it is concentrated k2so4 and in case of conc so4 ion we choose so4 ion although we choose upper elemnt which is oh- ion but this is exception in case of so4-2 that for conc we choose it
