Concept explainers
(a)
Interpretation:
The reason as to why it is important to specify an identity of the anion in the given case even though it is a spectator ion.
Concept introduction:
Ionic strength of a solution is calculated by adding the concentration of each ion present in the solution after multiplying it by their corresponding charges. The ionic strength of the solution is represented as,
Where,
•
•
(b)
Interpretation:
The expected voltage for the given
Concept introduction:
Activity coefficient depends upon the charge and size of the ion, and on the properties of the solvent. Debye-Huckel limiting law, describes the relation between the ionic strength and activity coefficient of a dilute solution.
