Explanation:
State symbols are used in chemical equations to delineate the state of matter in which the reaction is taking place.
They give a good perspective of the state of the reactants and products obtainable.
There are basically four states of matter in every chemical reaction:
- Solids are symbolized by small letter (s)
- Liquids are represented by (l)
- Gases are shown by (g)
- Aqueous solutions having water as the medium by (aq)
These symbols appear as subscript in front of the chemical species.
According to one acid-base theory, a water molecule acts as an acid when the water molecule (3) donates an H+.
