Question

Why we use methyl orange for the titration of sodium hydroxide against hydrochloric acid?

Answer 1

Answer:

Explanation:

Mainly 2 types of indicators are used in acid base  titration,namely:

• Phenolphthalein
• Methyl orange

But which indicator is used,depends upon the strength of the base.

If strong base is used,then methyl orange is used as indicator ( light orange colour).

If weak base is used,then phenolphthalein is used as indicator (pink colour).
