A dilution means the solution obtained by adding a solvent to a concentrated solution. By adding the solvent the concentration of the dissolved substance is reduced.

An example of a solvent is water, which has the characteristic of reducing the concentration of many solutions.

An example of dilution can be the following: liquid soap concentrated in 500ml water is added in a ratio of 1:30. This means that we will use one part soap to 30 parts water.

The calculation formula is as follows:

Tp = 1 + Rd (Tp = 1+30 = 31)

Tsn = Ts : Tp (Tsn = 500 : 31 = 16,13ml)

Ns = Ts - Tsn (Ns = 500 - 16,13 = 483,87ml)

where

Tp = Total parts solution

Rd = Dilution ratio (ex. 20 from 1:20)

Tsn = Total solution needed to dilute

Ts = Total resulting solution

Ns = Need solvent

The module is below:

The field *Total solution* means the total amount of solution we want to get.

The field *Proportion (1:X) *means the dilution ratio of the solution. At a ratio of 1:30 X is 30 and it is entered in the form.

When you press the button *Calculated* the result will be displayed in the next 2 fields.

The field *Initial liquid: ml* means the initial amount of solvent.

The field *Liquid to add: ml* means the amount of solution added to the solvent.
