when salt is added to ice, salt being an impurity, reduces the inter molecular space between ice molecules. As we know that ice, in order to melt, contracts, i.e reduces the inter molecular space between its molecules. salt increases this activity and so ice melts at a lower temperature than it usually does. i.e salt decreases the melting point of ice.
