Dilution techniques are methods used to reduce the concentration of a substance in a solution. This is often achieved by adding a solvent, such as water, to the original solution. Common applications include preparing solutions for laboratory experiments or adjusting the strength of medications. There are various types of dilution techniques, including serial dilution and simple dilution. In a serial dilution, a series of dilutions are made, each reducing the concentration further. Simple dilution involves mixing a specific volume of concentrated solution with a solvent to achieve the desired concentration directly.
