Answer 1

Reddish brown colour highly deliquescent salt is of Ferric Chloride.

Explanation:

• When to a  ferric chloride solution sodium hydroxide is added , a reddish brown precipitate is formed in the solution.

• here the anhydrous ferric chloride FeCl3 is deliquescent in nature.
• The reaction helps to  forms hydrated hydrogen chloride mists on reaction with moist air.

• The ferric chloride so formed is a deliquescent .
• This means it forms hydrated hydrogen chloride which reacts with moist air.
• Deliquescent is a nature of the salt which absorbs the moisture present in the air,
