Which is a chemical property of soda ash?
it's a highly basic substance.
it's a white crystalline powder.
it can dissolve in water.
it can be separated from water by distillation.

Option (a) is the correct answer.

Explanation:

A property which can be observed when the chemical composition of the substance changes is referred to as chemical property.

For example, melting point, acidity, basicity, boiling point etc are all chemical properties of a substance.

In the given options, it's a white crystalline powder, it can dissolve in water and it can be separated from water by distillation, these all represent the physical property and no change in the chemical composition of soda ash.

Thus, we can conclude that it's a highly basic substance is a chemical property of soda ash.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
