Question

you are provided with a solution which is bitter in taste and soapy in touch. it is used to manufacture soap. What will happen if a drop of methyl orange is added to it

Answer 1

Because the solution provided to you is soapy to touch and is very bitter to taste, we can deduce that it is base.

Since the solution is soapy, it means that sodium hydroxide is used to make this solution.

When a drop of methyl orange is added to the solution, the methyl orange becomes yellow in color.

Answer 2

Indicators of that solution :

Soapy to touch

Bitter to taste.

Well these indicate that the given solution is base. Since Bases are generally bitter to taste and soapy to touch. When Methyl Orange is added to a Base we get a yellow colour in the solution.

If it is neutral then it would have remained orange colour. If in acid means, it would be slightly Orangish red.
