Why does the phenolphthalein turn pink?
Complete step by step solution: -Phenolphthalein is widely used as an indicator in acid-base titrations. -It turns colourless in presence of an acid and turns pink in presence of a base. It is due to the formation of ions that the solution turns pink.
What is the difference between phenolphthalein and methyl orange?
Methyl orange indicator gives red colour in acid while phenolphthalein is colorless in acid solution. Methyl orange gives yellow in basic while phenolphthalein gives pink colour in basic solution..

What Colour is methyl orange in neutral?
yellow
Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately. The point of change is at pH 4.3.
Is methyl orange orange in colour?
The colour change of methyl orange depends upon the pH of the solution. In acidic medium means pH below 3.0 it shows red colour. In the range 3.0−4.5 pH, Methyl orange is of orange colour and in basic medium shows yellow colour.
What colour is phenolphthalein?
phenolphthalein, (C20H14O4), an organic compound of the phthalein family that is widely employed as an acid-base indicator. As an indicator of a solution’s pH, phenolphthalein is colourless below pH 8.5 and attains a pink to deep red hue above pH 9.0.
What does methyl orange do?
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 pKa of a mid strength acid, it is usually used in titration for acids.
Is methyl orange acid or base?
Methyl Orange is a weak acid which dissociates in water forming orange neutral molecules. Under acidic conditions, the equilibrium is to the left, and the concentration of the neutral molecules is too low for the orange colour to be observed.
