उत्तर
A solution made in water is known as an aqueous solution and indicated by the symbol (aq).
Explanation:
The term aqueous comes from the Latin word aqua, meaning water, which acts as the solvent that dissolves the substance. In chemical equations, the symbol (aq) is placed directly after a chemical formula to specify its state. For example, writing NaCl(aq) shows that common table salt is completely dissolved in water rather than being a solid.
