Q:

What measuring device is used to determine the density of a liquid solution?

A:

One common instrument that measures the density of a liquid solution is a hydrometer. Hydrometers can be broadly classified into four types based on their function. These include lactometers, saccharometers, salinometers and alcoholometers.

Density is one of the defining properties of matter. It can be mathematically represented using the formula d = m/v, where "d" indicates density, "m" denotes mass and "v" is the volume.

Liquid solutions are homogeneous mixtures containing a substance called a solute that is dissolved in a liquid solvent. To determine the quality and proportions present in a liquid solution, the density is measured using a hydrometer.

A hydrometer is designed using a weighted bulb encased in a calibrated glass tube. The hydrometer is submerged and the height at which it stops is equal to the density of the liquid. Most hydrometers are also equipped with internal thermometers to increase accuracy levels.
