Question

After heating salt, common salt and ammonium chloride for a few minutes, we observe the following on the upper part of the inverted funnel:
a)a reddish brown deposit
b)a white solid deposit
c)water droplets
a yellow gas

Answer 1

Answer:

After heating salt, common salt and ammonium chloride for a few minutes, we observe the following on the upper part of the inverted funnel:

b)a white solid deposit

Answer 2

A white solid deposit is obtained on the upper part of the inverted funnel by heating a mixture of common salt and ammonium chloride. So option (b) is correct.

• Ammonium chloride can exhibit the property of sublimation, which involves the conversion of a substance in the solid phase to a gaseous state directly. The liquid state formation is not involved in this process.
• Ammonium chloride on heating converts to the gaseous state, which on condensation deposits as a white solid on the upper part of the inverted funnel.
• Sodium chloride remains intact in the sample holder dish.
• This method of sublimation is used to separate a mixture of ammonium and sodium chloride.
