Question

In the electrolysis of aqueous NaCl, how many grams of Cl2 are generated by a current of 4.65 amperes flowing for 340 minutes?

Expert Solution
Step 1

Question is based on first law Faraday's law of electrolytes. i.e., amount of substance deposited is directly proportional to charge supplied during electrolysis.

To find out total charge supplied from equation is Q=It

charge present on 1 mol of electrons i.e, 1 faraday or 96500 coulombs

stoichiometry of the reduction occurring

Step 2

35.5 g of chlorine gas is evolved when 96500 coulombs of charge is supplied.

current supplied= 4.65 amp

Time period =340 minutes or 340×60 seconds 

96500 coulombs will release 35.5 g of chlorine 

4.65×340×60 coulombs will deposit = ?
