WebMar 13, 2024 · One of the most used indicators in acid-base titrations is phenolphthalein whose acid form is colorless and its conjugate base is red (fucsia). The compounds listed have been selected so that their p Ka values are approximately two units apart. Consequently, they offer a series of color changes spanning the whole pH range. WebAcid - Base indicators (also known as pH indicators) are substances which change colour with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions. Consider an indicator which is a weak acid, with the formula HIn. WebThe presence of much water causes the red colour of a faintly acid solution of methyl orange to become yellow, probably due to hydrolytic dissociation. The indicator solution generally used is prepared by dissolving 0.1gm in 100cc of distilled water.
