What the Colour Change Tells You
A red or pink result is a clear sign of acid. A strip that stays blue, or turns only purple, cannot by itself tell a neutral solution from an alkaline one, so test the same solution with red litmus as well: red litmus turning blue confirms a base. For a numerical pH, move on to universal indicator paper.
Handling the Vial
Take out strips with dry fingers or forceps and replace the cap straight away, because damp air and acid fumes in a laboratory can tint the unused strips. Lay a strip on a white tile and apply the solution with a glass rod or dropper rather than dipping it into a stock bottle.
