ambhoreanandow2iic: Universal indicator is a mixture of coloured compounds, which is used for simple testing of solutions. It is of no use for titrations as there are several colour changes that take place over a variety of pH values.

ambhoreanandow2iic: Litmus is a vegetable based dye that was used in schools before the advent of universal indicator. It has a simple colour scheme, in acids it turns red and in bases it turns blue, however the mid-point is not sharply defined and is unsuitable for titrations.

Litmus paper when previously dampened can also be used to test for the acidity of gases.

ambhoreanandow2iic: Phenolphthalein is an organic indicator with a pKa value of 9.3. It is red in bases and colourless in acids.

ambhoreanandow2iic: Methyl orange is an acid base indicator that turns red in acidic solution and yellow in base, the mid-point colour is orange. Its pKa value is 3.4.
