write a note on colorimeter

Answer 1

$\huge\Black {Answer}$

A colorimeter is a device used for measuring colours, or colorimetry. It measures the absorbance of different wavelengths of light in a solution. It can be used to measure the concentration of a known solute.

Different chemical substances absorb different wavelengths of light. When the concentration of the solute is higher, it absorbs more light in a specific wavelength. This is known as the Beer-Lambert law.
