Reagent strips change color by reacting with specific substances present in the sample being tested. This reaction causes a chemical change, resulting in a visible color change on the strip. The intensity of the color change can indicate the concentration of the target substance in the sample.
This is the diffusion of the coloring agent molecules in water.
Nitrile gloves can change color due to exposure to light, heat, or chemicals. This can lead to discoloration or yellowing of the gloves over time. It is important to store nitrile gloves properly in a cool, dark place to prevent color change.
Proteins can change color due to denaturation, which alters their structure and causes them to reflect light differently. This change can be caused by factors such as heat, pH fluctuations, or exposure to chemicals, leading to a change in the protein's appearance and color.
