Question

Ice should be prepared using distlled water to determine the melting point. Give reason

Answer 1

Answer:

Melting point of ice which is form from distilled water is 0°C. If the ice is form from sea water then its melting point decreases because salt lowers the melting point of water. Because the sea water is made of salt ions and water molecules, the salt ions replace some of water molecules.
