This Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm. While it seems simple, adding salt to ice water actually activates two complex, and contradictory, chemical reactions. The salt disrupts the equilibrium of water and ice, slowing down the amount of water freezing into ice and speeding up the amount of ice melting into water. However, because of this disruption, salt lowers the temperature of the water, making the overall melting rate decrease. Which reaction will win out? We’ll also test the effect of sugar on ice.
