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.
What is the colour change of carrot indicator in acid medium?
Carrot indicator turns yellow in an acidic medium. This change in color is due to the presence of anthocyanins that react with the acidic solution.
What color does litmus paper change when added to HCL and methyl benzene?
Litmus paper will turn red in the presence of HCl, indicating acidity. However, it will not show any significant color change when added to methyl benzene, as it is a nonpolar solvent and does not react with litmus paper to cause a color change.
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.
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
Is azospirillum gram positive or gramnegative?
Azospirillum is a Gram-negative bacterium.
Is azospirillum a gram positive bacteria?
Gram positive

Explain how a citrate-positive organism might not produce a color change in the medium?
This is because of incomplete incubation.
Is Medium skin color light?
Medium skin color is not very light.. Ivory is.
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.

Litmus paper will turn red in the presence of HCl, indicating acidity. However, it will not show any significant color change when added to methyl benzene, as it is a nonpolar solvent and does not react with litmus paper to cause a color change.
How does the speed of light of different colors passing through the same medium vary?
The speed of light of different colors passing through the same medium remains the same. This is because the speed of light in a medium is constant and does not change based on the color of the light.
How does turmeric changes it colour in an alkaline medium?

Why will the color of the sun change from yellow to red when it becomes giant?
Color is related to surface temperature, and a "red giant" is cooler than a main sequence, medium-sized star like the Sun.
