When H 2 S O 4 is electrolysed, there are two different anion presents in solution O H ?, S O 4 2 ? . But as oxidation potential of hydroxide ion is higher so it will oxidise first.

On electrolysis of a solution of dilute H2SO4 between platinum electrodes, the gas evolved at the anode is:, Dilute sulfuric acid is used as the electrolyte in this investigation. The Hofmann voltameter is filled with the electrolyte (sulphuric acid) by opening the taps at the top of the outer tubes to allow any gas to escape. The gases formed on the electrolysis of the dilute sulfuric acid can be collected via the same taps.
dilute solution of sulfuric acid. sulfuric acid. H 2 SO 4 (aq) but can be sulfate salts of reactive metals whose ions are not discharged, and alkaline hydroxides of reactive metals like sodium hydroxide: hydrogen gas: 2H + (aq) + 2e – ==> H 2(g) or 2H 3 O + (aq) + 2e – ==> H 2(g) + 2H 2 O (l) oxygen gas (i) 4OH – (aq) – 4e – ==> 2H 2 O (l) + O 2(g), Dilute H2SO4 was taken in an electrolytic cell and electric current was passed through it. What are the changes seen in it and give reason? Answer: On electrolysing dilute solutions of gases are produced at both the anode and the cathode electrode.

9/19/2011 · Favorite Answer. When a dilute solution of H2SO4 is subjected to electrolysis, the effect is to convert the water to hydrogen and oxygen. This is equivalent to removing water from the solution. The…
10/22/2017 · Whenever Dil. Solution of H2SO4 is electrolysed it produces gases at Cathode as well as anode. Reaction involved. At Catode 2 H + + 2 e ? ?H2. At Anode 4 O H ? ?4 e ? + 2H2O + O2. Gas on Cathode can be detected by taking a matchstick towards it. If it burns with sound of pop,this shows the presence of H2SO4. Gas produc, However, do take note that they are in fact heavily solvated in aqueous solution. In some textbooks, it may be said that for the electrolysis of dilute H 2 S O 4, the oxidation half-equation is written as 2 H X + + 2 e X ? ? H X 2 and the reduction half-equation is written as 4 O H X ? ? 2 H X 2 O + O X 2 + 4 e X ?.
