To count the number of ions in a equation you will use a net ionic equation. To start with a net ionic equation start with a balanced equation, and break all soluble strong electrolytes.
If the dissociation equation is:2 H2O-------------(H3O)+ + (OH)-the number of ions is 12,044281714.10e23.
Only if you know how many moles there are.
The coefficient represents the number of atoms, molecules, ions, or moles of a substance.
A subscript indicates the number of atoms or ions of an element in a chemical formula.
The equation is: H2O------>H+ + OH-
By removing from the complete equation any ions that occur in the same number on both sides of the complete equation.
If the dissociation equation is:2 H2O-------------(H3O)+ + (OH)-the number of ions is 12,044281714.10e23.
Only if you know how many moles there are.
Carry out all the multiplications and divisions and then count them.
The total ionic equation shows all of the equation, even the spectator ions. The net ionic equation shows the net change after spectator ions have been removed.
The coefficient represents the number of atoms, molecules, ions, or moles of a substance.
A subscript indicates the number of atoms or ions of an element in a chemical formula.

The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
Constituent Ions are Spectator Ions. Spectator Ions are ions that appear on both sides of the chemical equation. (Spectator Ions appear as both reactants and as products). They do not participate in the reaction and they are NOT shown in the Net Ionic Equation.
