Answer» Solution 'A' gives a white sulphide precipitate with group IV reagent. Its precipitate dissolves in dil.HCl to give solution 'B'. A bluish white precipitate appears when potassium ferrocyanide $(K_{4} F e (C N)_{6})$ solution is added to the solution 'B' after neutralisation by $N H_{4} O H$ solution. The cation present in solution 'A' is
