Question

give a balanced equation for conversion of - (a) an ammonium salt to a basic gas and (b) a soluble lead salt to an insoluble lead salt - formed as a white precipitate

Answer 1

NH4CL+Ca(oH)2 ............Cacl2 +H2o+NH3 .. You can use any ammonium salt just make sure you use calcium hydroxide with it (b)Pb(No3)2 + NH4CL......Pbcl2 +NH4No3...note lead chloride is a white ppt which is insoluble is excess ammonia or ammonium salt
