Question

weak acidic indicator among the following is a) phenophthalein b) Methyl orange c) Litmus d) Methyl red​

Answer 1

b) Methyl orange

Methyl orange is a pH indicator frequently used in titration because of its clear and distinct color variance at different pH values. Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the pH of a mid strength acid, it is usually used in titration for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point.
