What is indicator which has no color with the acidic medium?
Litmus paper is an indicator that has no color in an acidic medium. It turns red in acidic solutions and blue in basic solutions.
Why do indicators change colors?
Indicators change colors to signal a shift in a particular condition or state. This color change helps individuals quickly and easily understand the status or result being conveyed without needing to interpret detailed information.
How does turmeric changes it colour in an alkaline medium?
Turmeric contains pigments called curcuminoids, which change color at different pH levels. In an alkaline environment, the curcuminoids tend to turn a more vibrant red or pink color, due to a change in their chemical structure. This color change is reversible and is often used as an indicator in laboratory experiments.
What name is given to an indicator which gives different odor in different medium?
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.
What does a color change in an acid-base titration mean?
A color change in an acid-base titration indicates the endpoint of the reaction, where the amount of acid or base has been completely neutralized. This change is often detected using a pH indicator that changes color based on the pH of the solution. The color change helps in determining the equivalence point of the titration.
Why indicator change color?
Indicators are mostly organic aromatic compounds in acidic to basic medium or vice versa the resonating structures of indicators become change which are responsible to change the colour.
What is indicator which has no color with the acidic medium?
Litmus paper is an indicator that has no color in an acidic medium. It turns red in acidic solutions and blue in basic solutions.
How much does a medium carrot weigh?
A medium carrot weigh about 2.5 ounces
What colour does universal indicator turn in ammonia solution?
Universal indicator turns blue or purple in ammonia solution. Ammonia is a weak base, so it causes the indicator to change to a blue or purple color on the pH scale. This color change indicates the basic nature of the solution due to the presence of ammonia molecules.
Why do indicators change colors?
Indicators change colors to signal a shift in a particular condition or state. This color change helps individuals quickly and easily understand the status or result being conveyed without needing to interpret detailed information.
How do you determine the indicator constant?
The indicator constant is typically determined experimentally by monitoring the change in the indicator's color as the pH of the solution changes. The pH at which the color change occurs is the indicator constant. This value can also be found in literature references for commonly used indicators.

What does a blue or pink color in thioglycollate mean?
A blue color in thioglycollate indicates the presence of oxygen in the growth medium, as oxygenated environments turn the indicator dye blue. In contrast, a pink color signifies that the medium is anaerobic, as the dye is reduced in the absence of oxygen, turning pink.
