Question

A mixture of powdered salt and sugar can be separated by the process of winnowing (True or False)

• A. True
• B. False

Answer 1

The correct option is B False

• Winnowing is the process in which the heavy particles get separated from the lighter particles by the action of wind.
• Evaporation is a process in which a phase transition occurs from the liquid phase to the gaseous phase.
• A mixture of salt and sugar can be separated by evaporation.
• Salt and sugar form a homogenous mixture when dissolved in water.
• During evaporation, if the water gets evaporated completely. Now, the mixture that is left is dissolved in alcohol,
• Sugar can dissolve in alcohol, but salt cannot dissolve in alcohol so the salt gets separated as the sugar dissolve with alcohol and further filtration will be done in order to get salt.

Thus, the mixture of salt and sugar can be separated by evaporation.

Hence, the given statement is false.
