Concept explainers
Interpretation:
The balanced and net ionic equation for the reaction of magnesium hydroxide with hydrochloric acid should be written.
Concept introduction:
The law of conservation of mass states that no atoms can be created or destroyed in a
Ionic equation is an equation in which ions are explicitly shown.
Spectator ions are the ion that appears unchanged on both sides of a reaction arrow.
Net ionic equation is the chemical equation for a reaction which lists only those species participating in the reaction.
To write the net ionic equation, steps mentioned below must be followed.
- 1. Write the balanced molecular equation
- 2. Write the ionic equation showing the strong electrolytes completely dissociated into cations and anions.
- 3. Cancel the spectator ions on both sides of the ionic equation.
- 4. Check that charges and number of atoms are balanced in the net ionic equation.
