Question

You begin pouring sodium chloride into a glass of water. For a long time, the sodium chloride just dissolves in the water, but suddenly it begins to pile up at the bottom of the glass. Which statement is true?

Answer 1

The options are:

A. The sodium chloride has increased the temperature of the water.

B.he sodium chloride has decreased the temperature of the water.

C.The water is unsaturated.

D. The water is saturated

Answer:

D

Explanation:

An unsaturated solution is one that doesn't have as much solute as it could take. This is the reason why the sodium hydroxide kept dissolving as it was added until at a point where the solution has taken as much solute as it could hold.From that point any additional sodium hydroxide added wont dissolve and would pile up at the bottom of the glass
