The colour of an indicator must change because of something, like pH. A dye is just coloured, like food dye.
An indicator is a substance that changes color in response to changes in pH levels, while a dye is a substance used to impart color to an object. Indicators are typically used in chemical analysis to determine the acidity or basicity of a solution, whereas dyes are commonly used in textiles, cosmetics, and food industry for coloring purposes.
The color of an indicator must change because of something, like pH. A dye remains a constant color, like food dye.
no they are not
True. One method for detecting the endpoint of a titration is indeed using an indicator dye that changes color at different pH values. The color change of the indicator dye can be observed to determine when the reaction between the titrant and analyte is complete.
Crystal violet is a triphenylmethane dye that can act as an acid-base indicator. In acidic solutions, it appears as a red color, while in basic solutions, it turns blue or violet. This color change is due to the different protonation states of the dye molecule at different pH levels.
This indicator is known as an olfactory indicator. It changes its smell based on the pH of the medium it is in, which can be useful for detecting changes in acidity or alkalinity.
Different colors in fabric dye can be separated by a process called chromatography. In this process, the fabric dye is dissolved in a solvent and then the mixture is allowed to move up a strip of paper. As the solvent moves up the paper, different colors in the dye will separate and appear as distinct bands.
Indicator ion exchange resins are made by incorporating specific indicator dyes into the ion exchange resin matrix during the manufacturing process. These indicator dyes change color in the presence of certain ions, allowing for easy visual identification of their presence or absence in a solution. The choice of indicator dye will depend on the specific ions to be detected.

Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
Your question makes no scene.
Resazurin dye is used in microbiological culture media for anaerobes as an indicator of the presence of oxygen. The dye turns pink when oxygen is present.
just don't ask me i hate chemistry.
a calcein is a fluorescent dye, used in some cases as a calcium indicator.

acid base indicator
Lac+ bacteria is acid base color indicator that lowers the pH of the MacConkey agar. The MacConkey agar contains neutral red dye, lactose, peptone, and crystal violet dye.
This indicator is known as an olfactory indicator. It changes its smell based on the pH of the medium it is in, which can be useful for detecting changes in acidity or alkalinity.
Bromothymol blue is used as a pH indicator to detect acidity or alkalinity in a solution. It turns yellow in acidic solutions and blue in alkaline solutions, making it a useful tool for visualizing changes in pH during experiments or in the lab.
the project name of different type of tie-dye?
