Match the column :
`{:("Column-I","Column-II"),((A)"Molten" PbCl_2 "using inert electrode", (p)"Metal of salt will reduced"),((B)"Sodium chloride solution using inert electrode ",(q)H_2O+2e to H_2(g)+2OH^(-)),((C )"Silver nitrate solution with silver electrode",(r)"Solution become basic after electrolysis"),((D)"Sodium nitrate solution using inert electrode",(s)"Solution become neutral after electrolysis "),(,(t)"Solution become acidic after electrolysis"):}`

Answer

A-p,s , B-q,r , C-p,s , D-q,s

Explanation

(A)`PbCl_2, "Cathode" : Pb^(2+)+2e^(-)to Pb(s)`
Anode : `2Cl^(-)to Cl_2(g)+2e^(-)`
(B)`"Cathode" : H_2O+2eto H_2(g)+2 OH^(-)`
Anode : `2Cl^(-)to Cl_2(g)+2e^(-)`
( C)`"Cathode" : Ag^(+)+e^(-)to Ag(s)`
Anode : `Ag(s)underset("Neutral solution")(to Ag^(+)+e^(-))`
( D)`"Cathode" : H_2O+2eto H_2(aq)+2OH^(-)`
Anode : `H_2Ounderset("Neutral solution")(to 1//2O_2+2H^(+)+2e^(-))`
