Question

What is the name of an instrument used to measure the absorbance of a coloured compound in solution

Answer 1

A colorimeter is an instrument that determines the concentration of a solution by measuring its absorbance of a specific wavelength of light, as the concentration is proportional to the absorbance (Beer–Lambert law).

Answer 2

Answer:

Calorimetry

Explanation:

Colorimetric methods are used commonly to analyze concentrations of specific ions. These methods are based on formation of a specific colored compound from the ion of interest. The concentration of the colored compound can then be determined with a spectrophotometer (a machine that measures the absorption of light at specific wavelengths).
