B. The solution turns pink
C. The solution turns colourless
D. The solution turns purple​

Answer 1

Answer:

A) The solution turns into yellow

Answer 2

Answer:

Option(a) the solution turns yellow

Explanation:

Methyl orange is a pH indicator used in titrations because of its clear and distinct colour change. It shows red colour in acidic and yellow colour in basic medium.

Electrolysis of brine or sodium chloride solution produces sodium hydroxide, NaOH which is a strong base. Using methyl orange as an indicator gives a yellow colour solution for NaOH.
