(a)
Interpretation:
Balanced net ionic equation for the reaction has to be determined.
Concept introduction:
Net ionic equation is used to show only the chemicals and ions involved in a
Steps involved in balancing the net ionic equation is
Step.1- Write the unbalanced net ionic equation.
Step.2- Decide which atoms are oxidized and which are reduced and write the two unbalanced half-reactions.
Step 3- Balance both half-reactions for all atoms except
Step 4- Balance each half reaction for
Step 5- Balance each half-reactions for charge by adding the electrons to the side with greater positive charge and then multiply by suitable factors to make the electron count the same in both half-reactions.
Step 6- Add the two balanced half-reactions together and cancel electrons and other species that appear on the sides of the equation.
(b)
Interpretation:
Concentration of all the ions in the solution after reaction to make it electrically neutral has to be calculated.
Concept Introduction:
Molarity
So,
Concentration of ion is the ionic strength in the solution when dissolved in water.
