Indicates whether the substance is an acid or alkali.
What chemical indicators are and what they are used for?
chemical indicators are completely an organic solutions that changes color in the solution we added them to it due to the change in PH.....they are used to determine the equevelant point and the end point in titration
Is anti- acid tablets in water a chemical reaction or physical change?
it is a chemical process due to changes in pH occur, which are held to chemical processes. :)
What is a chemical dye that changes color based on the pH of a solution called?

Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
What is used to identify an acid or a base?
the pH of the substance
How can you identify if a chemical is an acid?
A chemical can be identified as an acid by testing its pH. A pH value less than seven is considered acidic, while a pH value greater than seven is considered to be a base, or alkaline. Pure water has a pH value of seven.

Is it false that Indicator paper is used to identify acids and bases?
A pH indicator paper can be used to tell if a solution is acidic or basic and the rough pH range can be known
