Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
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.
You would determine the concentration of an acid by titrating it with a base of known concentration. The point at which the acid is neutralized by the base (equivalence point) can be detected using an indicator or a pH meter. By measuring the volume of the base needed to reach the equivalence point, you can calculate the concentration of the acid using the equation C1V1 = C2V2, where C1 is the concentration of the acid, V1 is the volume of acid used, C2 is the concentration of the base, and V2 is the volume of the base used.
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.
