A contraction is a decrease in the total volume of two liquids when they are mixed.
A table from a word file will be useful to all those who need to calculate how much “output” this or that product will turn out, for example, from a liter of alcohol and a liter of water, not 2 liters of the mixture is obtained, but less.

More about the issue of contraction
The reason for the contraction of, for example, an alcohol-water mixture is the addition of several water molecules by alcohol, but not in the form of a chemical compound, but in the form of physical retention due to the interaction forces of the electric fields of the molecules.
As a result, the size of the molecule increases and the density of the solution increases. One molecule of alcohol attaches a different number of water molecules at different concentrations of alcohol, and the greatest compression of the mixture occurs at an alcohol content of about 46%.
When alcohol is diluted, the mixture heats up, and this, as you know, is a sign of a chemical reaction. Water combines with alcohol to form hydrates. The bond is non-covalent, but strong enough.
Due to the bond, the molecules of water and alcohol come closer to each other, which means that the liquid becomes denser – the volume decreases. The reaction takes place completely in about a day, so freshly diluted alcohol is a little harsh.
