Question

How will you provide the following information in a chemical equation?

An aqueous solution.

Answer 1

Aqueous solution means a solution that is made by using water as the solvent.

In a chemical equation, if a compound is in its aqueous form, it can be represented by adding (aq) just adjacent to the required compound.

For example:

$$\begin{gathered} 2\mathrm{Na}\left(\mathrm{s}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to 2\mathrm{NaOH}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \left(\mathrm{Sodium}\right)\left(\mathrm{water}\right)(\mathrm{Sodium}\mathrm{hydroxide})(\mathrm{Hydrogen}\mathrm{gas}) \end{gathered}$$

In this equation, the Sodium hydroxide is in its aqueous state. Hence, (aq) is written adjacent to it in the chemical equation.
