• It is derived from a Greek word meaning 'liquid'.

• It is a modern scientific term with no historical origin.

• It comes from a Latin word meaning 'water'.

Which of the following is an example of an aqueous solution?

• Oil mixed with water

• Salt dissolved in water

• Petroleum in water

• Sand in water

Why is water known as a universal solvent?

• Because it is the only solvent used in chemistry.

• Because it can dissolve all substances.

• Because it can dissolve a large number of substances.

• Because it is a non-polar compound.

Which type of compounds are generally soluble in water?

What happens to ionic compounds like salt when dissolved in water?

• They dissociate into ions.

• They remain unchanged.

• They evaporate.

• They form a new compound.

What does the subscript 'aq' indicate in a chemical formula?

• The compound is in a gaseous state.

• The compound is in a solid state.

• The compound is in a liquid state.

• The compound is in an aqueous solution.

Which of the following aqueous solutions can conduct electricity?

• Conductors

• Non-electrolytes

• Electrolytes

Why are aqueous solutions important in daily life?

• They are used only in industrial processes.

• They are crucial for human and animal survival.

• They are only used in laboratory experiments.

• They are not important outside of chemistry.

Which of the following is NOT a characteristic of an aqueous solution?
