phenol red and litmus paper can indicate an acid or base
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.
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.
Phenolphthalein is used in titration experiments as an acid-base indicator because it changes color at a specific pH range (pH 8.2-10.0), making it easy to visually detect the endpoint of the titration when the solution changes from acidic to basic or vice versa. This helps in determining the volume of titrant needed to reach the equivalence point accurately.
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.

Yes - it's used in acid-base titration.
an indicator used for weak acid nd strong base
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.
An acid base indicator is used for determining the pH of a solution, and determining if it is an acid, a base, or neutral solution. Red-ox indicators are used to check whether a desired red-ox reaction has proceeded to its completion.
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
Phenolphthalein is commonly used as an indicator in acid-base titrations because it changes color sharply within a specific pH range (approximately 8.2 to 10). In an acid-base titration, the endpoint is reached when the solution becomes either pink (indicating a basic solution) or colorless (indicating an acidic solution), making it easy to detect the completion of the reaction.
