# Mixtures

 Property 1 Portion 1 Quantity 1 Property x Property 2 Portion 2 Quantity 2 Quantity x

The results have been rounded to significant digits.

This calculator may be used to calculate how much of two solutions with different concentrations you must mix to get a mixture with a certain concentration. You may also calculate, which concentration (or temperature) you receive when you mix two liquids with different concentrations (or temperature).

The portions of the two components, displayed in the grey fields, are calculated by substraction of the values of the properties (portion 1 = abs (property 1 - property x) and portion 2 = abs (property 2 - property x)). This method sometimes is called "mixing cross".

ATTENTION: Effects like a change of the volume (or a change of the density) that may happen during the mixing process, are not considered and may lead to different results than calculated.

Usage: Use the light input fields to type 4 input values into the corresponding fields. The calculation is performed after a further click with the mouse on any free space of the window or on the "calculate" button. The grey fields that show the portions of the components following the method of the "mixing cross" cannot be used for input.
The calculation is performed using the values in those four input fields changed last. After the calculation, these fields are coloured lightgreen while the fields displaying calculated values are coloured pink. For another calculation with other values just type these into the corresponding fields. In the case that you want to do another calculation with completely different input, type the "reset" button.

Example: You have got hydrochloric acid of 20 weight-percent and need 100 g of an acid of 3 %. Type "20" into the input field for property 1 and type "0" into the field for property 2 (water). Into the field of the wanted property x type "3". After a click with the mouse on any free space of the window or on the "calculate" button the portions of the amounts are shown already in the grey fields: You must mix 3 parts of acid with 17 parts of water.
Now type the needed amount "100" into the field "Quantity x" and click on any free space of the window or on the "calculate" button. Read the result: You must mix 15 g of hydrochloric acid and 85 g of water to obtain 100 g of 3 % acid.

Remarks:
- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
