Question

Electrolysis of aq. K2SO4 using inert electrodes is carried out by passing 100 amperes for 965 seconds. Volume of the substance obtained at cathode(at STP) is

Easy
Solution

SRP value of EH+(aq)/12H2(1 atm), Pt(s)o>EK+(aq)/K(s)0

At cathode H2 gas is liberated

WH2=EitF WH2=1×100×96596500 WH2=1 g 2 g of hydrogen....22.4 l at STP 1 g......................11.2 l at STP
