To prevent table salt from absorbing moisture and to make it flow free

1.	To prevent table salt from absorbing moisture and to make it flow freely certain additives are added to table salt . Name one such compound and explain how does it work ?
Answer» SOLUTION :The additive is `Ca_(3)(PO_(4))_(2) or CA(H_(2)PO_(4))` which prevent moisture absorbing power of other compounds `(MgCl_(2) , CaCl_(2) , MgSO_(4) , CaSO_(4)`, ETC) present in table salt and thus keeps table salt dry . Further , both Ca and P are NEEDED by the human biological system and hence do not cause any side effect .
