Question

How to determine the relative density of salt using hydrometer

Answer 1

The relative density of salt using hydrometer can be determined as Thu below:

The liquid to test its relative density is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely.

• The point at which the surface of the liquid touches the stem of the hydrometer correlates to relative density.

What is density?

Density can simply be defined as the ratio of mass per unit volume of a substance.

So therefore, the relative density of salt using hydrometer can be determined as Thu below:

The liquid to test its relative density is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely.
