Question: 1 / 400

What effect does dissolving salt in water have on the specific gravity of the solution?

Increases the specific gravity

Dissolving salt in water increases the specific gravity of the solution. Specific gravity is a measure of the density of a solution compared to the density of pure water. When salt, which is more dense than water, is added to the water, it increases the overall mass of the solution without significantly increasing its volume. This results in a higher density, leading to an increase in specific gravity.

The addition of solutes like salt also affects the interactions between water molecules, resulting in a more compact arrangement and contributing to this increase in density. Consequently, the combination of increased mass and relatively unchanged volume is responsible for the elevated specific gravity when salt is dissolved in water.
