Apart from the electrodes, each one of the methods are visual and rely on some fundamental changes that take place in a molecule as soon as the pH of its environment changes. It is possible to gauge the pH of a solution utilizing universal indicator. Tactile indicators are ordinarily used in combination with visual indicators if an exceptionally speedy reaction to the incoming signals is needed.

Methyl orange is just one of the indicators commonly utilized in titrations. Litmus Litmus is the most frequently used natural chemical indicators used. Litmus solution and litmus paper are generally employed as an indicator.
