Expert Answer

Step 1

Spectrophotometer is a device consists of monochromator that produces a light beam containing a certain wavelengths which is passed through to the solution and absorbs at certain wavelength that can be used to determine the concentration of solution.

Step 2

The concentration of solution can be determined with the help of Beer-Lambert law. It states that quantity of light absorbed by a substance is directly proport...
