Differentiate the function of concentrated sulphuric acid as a drying agent & as a dehydrating agent. Is fused calcium chloride a dehydrating or a desiccating agent. Give reasons.

In the given equation - S+2H_(2)SO_(4)to3SO_(2)+2H_(2)O : Identify the role played by conc . H_(2)SO_(4) i.e. A : Non volatile acid B : Oxidisting agent C : Dehydrating agent D : None of the above .

Assertion : O_(3) acts as a powerful oxidising agent. Reason : O_(3) oxidises lead sulphide to lead sulphate and iodide ions to iodine.
