depends on the indicator used.

Does an acid or a base react with a predictable indicator to produce a color change?
both acid and base
What is the advantage of knowing the pKa of an acid-base indicator?
The advantage of knowing the pKa of an acid-base indicator is that it tells you the approximate pH value at which the color of the indicator changes. For example, if the pKa of an indicator is 5, then it means that it's going to change colors at around pH 5.
What does a color change in an acid-base titration mean?
according to change of PH of medium where the indicator color is changed according to PH of medium
How do you find out if it is acid or base without tasting it in a colourless liquid?
One could use the color change of lithmus paper or other acid/base pH-indicator commercially available.
Which indicator would be the best to show a change from an acid to a base?
phenolphthalin
What is acid base indicator?
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.

What will an indicator do in the presence of an acid or base?
This indicator changes his color.

What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
What are some indicators?

What are substances which exhibit a specific color in the presence of acid or base?
an indicator
what acid-base change color when in contact with an acid or a base?
pH indicators change the color in contact with acids or bases.
Which indicator would be the best to show a change from an acid to a base?
phenolphthalin
Which color does a base change when mixed with hibiscus indicator?
pink
