Explanation / Answer

A titration is used to determine the molarity of a speicific substance in a sample. A titration determines the Volume

of known Molarity that is required to react with a Volume of a sample of unknown Molarity .

An Indicator is used to identify the endpoint of a titration. the endpoint is the point at which enough of reagent of known concentration has been added to sample of unknown concentration to completely react with the Known solution. A color change will occur when endpoint is reached
