Chapter 25, Problem 25.5QAP
Interpretation Introduction
Interpretation:
The reason of necessity of a buffer solution in an electronic voltammetry should be determined.
Concept introduction:
The mixture of weak acid and the conjugate base of the weak acid or the mixture of the conjugate base of the weak acid and the weak acid in an aqueous solution is called buffer solution.

It will deliver 36 V if he connects three of these cells in series. Certain metals can be purified by electrolysis. A mixture of Ag, Zn, and Fe can be dissolved so that their metal ions are present in aqueous solution. If a solution containing these ions is electrolyzed, the zinc ions willhe reduced to zinc first. 3 Electrolysis of an aqueous magnesium iodide solution at standard conditions would form the following products: magnesium metal and iodine.
