What do you mean by colorimetry?

Colorimetry is a scientific technique that is used to determine the concentration of colored compounds in solutions by the application of the Beer–Lambert law, which states that the concentration of a solute is proportional to the absorbance.

What is colorimetry and its principle?

Colorimetry is the field of determining the concentration of a coloured compound in a solution. A colorimeter, also known as a filter photometer, is an analytical machine that acts as the tool quantify a solutions concentration by measuring the absorbance of a specific wavelength of light.

What is the application of colorimetry?

Colorimeters are used for a wide variety of applications in the chemical and biological fields including, but not limited to, analysis of blood, water, soil nutrients and foodstuffs, determination of solution concentration, determination of reaction levels, determination of bacterial crop growth.

How colorimetry is used in real world?

Colorimeters are widely used to monitor the growth of a bacterial or yeast culture. They provide reliable and highly accurate results when used for the assessment of color in bird plumage. They are used to measure and monitor the color in various foods and beverages, including vegetable products and sugar.

What is difference between spectrophotometer and colorimeter?

Moreover, a significant difference between colorimetry and spectrophotometry is that a colorimeter quantifies color by measuring three primary color components of light (red, green, blue), whereas a spectrophotometer measures the precise color in human-visible light wavelengths.

What is the difference between colorimetry and spectrophotometry?

The key difference between colorimetry and spectrophotometry is that colorimetry uses fixed wavelengths that only are in the visible range while spectrophotometry can use wavelengths in a wider range.

What are the limitations of colorimetry?

Disadvantages of Colorimetry

• The primary bottleneck of this method is that colorless compounds cannot be analyzed.
• It needs a huge amount of samples for analysis.
• It has low sensitivity.
• The same colors of interfering material can create errors in results.

What is the difference between colorimetry and spectroscopy?

What is colorimetry and spectroscopy?

Colorimetry or colourimetry is used to determine the concentration of coloured compounds in solution. The absorption is compared to a Calibration Graph- a graph of the different absorptions of standard solutions with known concentrations – to determine the concentration of the solution.
