Question

name the colour changing in methyl orange in acid and base....pls tell fast​

Answer 1

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 pK a of a mid strength acid, it is usually used in titration for acids.

Chemical formula: C₁₄H₁₄N₃NaO₃S

Melting point: > 300 °C (572 °F; 573 K) (not precisely defined)

Molar mass: 327.33 g·mol−1

Solubility in water: 0.5 g/100 mL (20 °C)

Explanation:

Answer 2

In a solution that decreases in acidity, methyl orange moves from the colour red to orange and finally to yellow with the opposite occurring for a solution increasing in acidity. In an acid, it is reddish and in alkali, it is yellow.
