During reaction of 2 chemical substances, the color produced asses by:
- a. Spectrophotometer***
- b. Flame photometer
- c. ELISA
- d. PCR.
The correct answer to assess the color produced during the reaction of two chemical substances is:a. Spectrophotometer
Here's why:
- Spectrophotometer:
This instrument measures the amount of light absorbed or transmitted by a substance at different wavelengths. By analyzing the specific wavelengths absorbed or emitted by the reaction product, you can determine its color. This is the most versatile and accurate method for assessing color in chemical reactions.
- Flame photometer:
This instrument analyzes the specific wavelengths of light emitted by elements when they are excited by heat. While it can be used to identify certain elements present in the reaction product, it cannot directly measure the color of the solution itself.
- ELISA:
This is an enzyme-linked immunosorbent assay, used to detect and quantify specific proteins or other molecules in a sample. It's not suitable for measuring color changes in chemical reactions.
PCR: This is a polymerase chain reaction, used to amplify and detect specific DNA sequences. It's not relevant to analyzing the color of a chemical reaction.
Therefore, the spectrophotometer is the most appropriate tool for assessing the color produced during the reaction of two chemical substances.
