What color of universal indicator in agar solution?
It depends on the pH.
What will be the colour of bromothymol blue in a solution of sodium chloride in water?
Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
Metacresol purple is an indicator that changes from yellow to purple at pH 8.2. what is Ka for this indicator and it's pH range and color of the solution with pH 9.0 and few drops of Metacresol purple?
6.3x10-9
A compound that can reversibly change color depending on conditions such as pH?
They are comonly known as "indicators" as the color change is useful for indicating what the pH of a solution is.
What changes color on pH?
a pH indicator
What color of universal indicator in agar solution?
It depends on the pH.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
How do you find the pH of an indicator?
Put a drop of universal indicator solution and observe the color change. Look online for the table.

Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
What is a chemical dye that changes color based on the pH of a solution called?
acid base indicator
Why did clothes turn red when stained with turmeric and washed with soap?
It is because the turmeric contains a compound called cucumine.cucumine reacts with the fatty acid in the soap/detergent and thence the color of the combination changes to red.

What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
Substance that is of one color in an acid solution and of another color in a basic solution is a what?
An acid-base indicator. Some examples are phenolphthalein and methyl orange.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
