If you mix a small amount of one substance with a large amount of another, the result is called “dilution.” The dilution ratio is the proportion of solute to solvent in a solution.

What is dilution?

It’s important to understand what dilution is because it’s a key aspect of chemistry. Dilution is the amount of water added to an original solution, or simply put the ratio of the volume of water to the volume of the original solution.

The math behind dilution isn’t too complicated:

  • First, we need to figure out how much water we’re adding (the total amount). This can be done by multiplying your desired ratio by 100%. For example, if you want your mixture to have a 1:2 ratio (one-part solution and two parts water), then multiplying each side by 100% yields 200% as a final answer—or two parts solution and four parts water will do nicely here!
  • Next, let’s figure out how much each component should be diluted with respect to their original amounts; this will require some basic algebraic manipulations involving ratios and percentages that we’ll go over below.

What is a solution?

In chemistry, dilution is the process of reducing the concentration of a solution. This can be done by adding solvent to it or removing some of the solvents from it. It also refers to a process in which different substances are mixed together to form new substances with different properties than either substance alone.

For example:

  • The solution will become less concentrated (less solute per volume) and may change color if there are any dyes in it.
  • The volume will increase due to the addition of more solvent, or decrease if you remove some of the solvents by evaporation or boiling away part of your mixture (this is called fractional distillation).
  • Masses do not change when you dilute something as long as there’s no chemical reaction involved; however, they might change if you’re mixing two completely different mixtures together because each mixture has its own mass before being mixed together into one larger batch–this means that when you mix them together you’ll have twice as much stuff overall so both masses would go up accordingly!

What is the dilution ratio?

The dilution ratio is the number of parts of solvent to each part of solute. It’s a measure of the concentration of a solution.

If you have 100 ml (milliliters) of water, and you add 1 ml (.001 L) of dye to it, then your dilution ratio would be 10:1 because you have 10 parts of water for every part of dye.

How do you calculate the dilution ratio?

Dilution is the ratio of the original amount of a solution to the new amount of that solution. It can be expressed as a fraction or decimal, and sometimes as a percentage.

If your concentration is 100%, you have only one ingredient in your solution. If you take some out, you’re diluting it. The more you take out, the more diluted the solution becomes!

Dilution ratio calculator – a practical example

For this one, there are no important formulas to mention, because it is as simple as dividing the concentrate volume by the water volume.

We hope this dilution ratio calculator has helped you with your calculations. It is a very simple tool, but it can be very useful for saving time when you are working on projects that involve dilution ratios and concentrations.


What is a 1: 4 dilution?

Imagine the dilution you have is made of 4 parts. Of those 4 parts, 1 is the concentrate and 3 parts are the diluent.

What does the 4:1 dilution ratio mean?

4:1 is the exact opposite of 1:4.

What is dilution?

Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing it with more solvent like adding more water to the solution.
