Question

What is the effect of impurity on the melting point of a pure solid?​

Answer 1

Answer:

A substance (solid) containing soluble impurities usually melts at a lower temperature than the pure compound. It can also melt over a wide range of temperatures and is called the “melting point depression.” In general, the smaller the range of melting temperatures, the higher the purity of the sample.

Answer 2

Answer:

Here you go ..........

Explanation:

Generally, when an impurity is added to a pure solid, the melting point of the solid decreases.

For example, we add rock salt on ice to melt it when there is way too much snow. In this case, snow or ice acts as pure solid and rock salt acts as an impurity. On adding rock salt the melting point of ice decreases which makes the ice to melt even at lower temperatures.
