What is the purpose of an acid base indicator?

An acid-base indicator is used to determine the pH of a solution by changing color at different pH levels. This visual change helps to identify whether a solution is acidic, basic, or neutral. It is commonly used in titrations and other chemical experiments to monitor the progress of a reaction.


What is the purpose of water washing the organic layer?

The purpose of water washing the organic layer is for aqueous extraction to remove impurities and or reagents that are water soluble. For instance, in reactions that utilize a small tertiary amine base or inorganic base.


What is added to an acid to maintain its pH?

A base is added to an acid to maintain its pH. Bases help neutralize the acidic solution by accepting hydrogen ions, thus raising the pH level closer to neutral. Common bases used for this purpose include sodium hydroxide and potassium hydroxide.


Give the chemical name of a common example of an acid or a base used to clean grease?

One of the main things used to clean grease is soap. Soap is a substance that is a base. Another popular spray cleaner uses bleach, which is also basic.


What is the purpose for using phenolphthalein for an acid base titration?

Phenolphthalein is used as an indicator in acid-base titrations because it changes color at a specific pH range. In an acid-base titration, phenolphthalein changes from colorless to pink when the solution reaches a pH around 8.2-10, indicating the endpoint of the titration. This allows for a visual indication of when the reaction is complete.
