Question

Write the symbols for all physical states.

Answer 1

Symbols of physical states of elements or compounds present in reactants and product are written to make the chemical equations more informative.

Symbols used to denote the physical states of elements and compounds:

For solid state: Small 's' is written in a bracket () after the element or compound to show the solid state.

For liquid state: Small 'l' is written in the bracket () after the element or compound to show the liquid state.

For gaseous state: Small 'g' is written in a bracket () after the element or compound to show the solid state.

For aqueous solution: 'aq' is written in the bracket after the compound to show the solution in water. This means ‘aq’ denote the aqueous solution.
