Principle

In this experiment, students observe the effect of salt on the melting point of water using a beaker filled with ice and water. They observe that after adding the salt, the ice melts and the temperature of the water in the beaker falls below 0°C. They conclude that the salt lowers the melting point of the water. They conclude that the salt lowers the melting point of the water, causing the ice to melt faster and the water to cool further than normal.
