What is the significance of symbol 'aq' in a chemical equation?
Answers
The symbol (aq) represents aqueous solution. When it is written after a chemical formula in a chemical equation, it represents that the element or compound is a aqueous solution i.e water is added into the solution.
Answer:
AQUEOUS SOLUTION.
Explanation:
An aqueous solution is a solution in which the solvent is water.
It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula.
For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq).
The word aqueous (comes from aqua) means pertaining to, related to, similar to, or dissolved in, water.
As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Aqueous solution is water with a pH of 7.0 where the hydrogen ions (H+) and hydroxide ions (OH-) are in Arrhenius balance (10-7).
