Question

What are the various ways to make the chemical equation more informative?

Accepted Answer

The various ways to make the chemical equation more informative are:

1) By indicating the physical states of reactants and products:

The solid state is indicated by the symbol (s), the liquid state is indicated by the symbol (l), the aqueous solution is indicated by the symbol (aq) and the gaseous state is indicated by the symbol (g). These symbols are called state symbols.

2) By indicating the heat changes accompanying the chemical equation. By adding or subtracting heat value in R.H.S.

3) By indicating the concentration of the acid or base. The terms like (dil) for dilute and (conc) for concentrated are used.

4) Conditions for the Occurrence of Reactions:

Some chemical reactions take place in presence of a catalyst or a metal or heat or at particular temperature etc. It can also be represented in the chemical equation by writing these conditions above or below the arrow mark drawn between the reactants and products.
