What is a Balance

The balance is the measuring instrument used to determine the masses of the objects.

Balances work because they compare the masses of a known standard and the object being measured.

The oldest balance was made up of two plates that hung at the ends of a horizontal bar, fixed in its center so that it was level when it was in balance.

Hence the term “balance” comes from the Latin bilanx, bi means “two” and lanx means “plate”, that is, “balance of two pans”.

The laboratory or chemical analytical balance it has to have high precision, since it must measure small masses of reagents to perform chemical analyses.

The term balance can be used as a synonym for: scale, weight, Roman, among others.
