Question

the colour is methyl orange indicator in basic medium is ___________​

Answer 1

Explanation:

yellow

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.

Answer 2

Answer:

Methyl orange which is used as an indicator gives yellow color in the basic medium.

Explanation:

Because of its obvious and distinct color variance at different pH levels, methyl orange is an often used pH indicator in titration. In an acidic media, methyl orange turns red, whereas, in a basic condition, it turns yellow.

The pH of the solution affects the color shift of methyl orange. It becomes red in an acidic media (pH less than 3.0). Methyl orange is of orange color in the pH range of 3.0-4.5 and of yellow color in the basic condition.

Because the pH of a neutral solution is around 7 and lowers following the color shift of methyl orange, it will be yellow in both basic and neutral solutions.
