Question

What does the symbol (aq) represent in a chemical equation?

Answer 1

Hint: A chemical equation shows the starting compound also known as reactant on the left hand side of the reaction and the final compound also known as the products on the right hand side of the reaction.

Complete answer:
While writing a chemical equation many symbols are used. Similarly, to describe the physical state of the reacting entities during the course of reaction many symbols are used which are mentioned below:
The symbol (s) is used for solid- state.
The symbol (l) is used to denote the liquid state.
The symbol (g) is used to denote the gaseous state.
The symbol (aq) is used to denote the aqueous solution.
Aqueous solution or (aq) means that the given substance is dissolved in water. The symbol (aq) comes from the word aqueous.

Additional information:
To write the chemical reaction we should first understand its participants:
The elements are represented by their symbol.
The reactants also known as the substrates are written on the left hand side of the chemical reaction and the products also known as the output of the chemical reaction are written on the right hand side of the chemical reaction.
An arrow is used to represent the direction in which the chemical reaction flows.

Note:
There are different types of arrows which are used while writing a chemical reaction and all these arrows have their own meaning. For example, “$\to $” symbol is read as “gives rise to” or “yields”.
