Concept explainers
(a)
Interpretation: Balanced net ionic equation for the reaction of given
Concept introduction:
Transition element is one which can form one or more stable ions with a partially occupied d-subshell. Most of the
Metal on reaction with an acid, the products are a salt and hydrogen gas.
When a metal reacts with sulfuric acid, the salt produced is a metal sulfate.
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.
