(a)
Interpretation:
Basic idea behind electrogravimetric analysis has to be determined.
Concept Introduction:
Electrogravimetric analysis is method used to determine weight of product. It is measured from the difference in weight of electrode before and after
(a)

Explanation of Solution
The basic idea of electrogravimetric analysis is if energy is supplied from external source to electrolytic cell then material is deposited on electrode rather than chemical precipitation from solution.
(b)
Interpretation:
Indication of completion of electrogravimetric deposition has to be determined.
Concept Introduction:
Electrogravimetric analysis is method used to determine weight of product. It is measured from the difference in weight of electrode before and after electrolysis.
(b)

Explanation of Solution
Completion of electrogravimetric deposition can be identified through disappearance of color if reactants are colored.
Also, completion of electrogravimetric deposition can be identified through qualitative analysis of solution.
