Answer 2

The indicator which does not change colour on passage of hydrogen chloride is phenolphthalein.

• There are various chemical indicators which give different colours according to the acidic or basic nature of the other chemical compounds.

• Similarly,the phenolphthalein is colourless in the normal conditions and it also stays colourless when it gets into the contact with the acidic substances.

• And, hydrogen chloride is also acidic in nature. That's why phenolphthalein doesn't change it's colour for the hydrogen chloride.
