(b) carbondioxide is passed through a concertrated aqueous solution of sodium chloride saturated with ammonia.
( c) red lead is treated with nitric acid.
(d) dilute nitric acid is slowly reacted with tin.

Answer 1

(a)`2SnCl_(2)+l_(2)to2SnCl_(2)l_(2)toSnCl_(4)+Snl_(4)`
(b)`NaCl+NH_(4)OH+CO_(2)toNAHCO_(3)+NH_(4)Cl`
( c)`Pb_(3)O_(4)+4HNO_(3) to 2Pb(NO_(3))_(2)+PbO_(2)+2H_(2)O`
(d)`Sn+10HNO_(3)`(dilute)`to 4Sn(NO_(3))_(2)+NH_(4)NO_(3)+3H_(2)O`
