Interpretation :
Difference between an aqueous solution and a liquid must be explained with symbols of each.
Concept Introduction :
Aqueous solution is the one in which some substance is dissolved in water. A liquid is a pure compound which is not a solution.

Answer to Problem 4RQ
In aqueous solution more than one species are present whereas in a liquid only one pure substance is present. For example aqueous solution of NaCl and molten (liquid) NaCl can be represented as NaCl (aq) and NaCl (l) respectively.
Explanation of Solution
A solute can be dissolved in water to form an aqueous solution which is a homogeneous mixture of the solute and water. But a pure liquid can be a substance which is liquid at room temperature or any solid is heated at its melting point to get the pure liquid.
Symbols for aqueous solution and liquid are ‘aq’ and ‘l’ respectively.
The difference between an aqueous solution and a liquid is explained along with the symbol of each.
