A) formation of the species \[{{[FeHP{{O}_{4}}]}^{+}}\]
B) lowering of potential upon complexation
C) formation of the species \[{{[FeS{{O}_{4}}]}^{+}}\]
D) high acidity of the medium
Correct Answer: A
Solution :
Since, \[{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\]and \[{{\text{H}}_{\text{3}}}\text{P}{{\text{O}}_{\text{4}}}\]both are strong acids so their presence makes the- medium more acidic. The \[\text{F}{{\text{e}}^{3+}}\]ions form complex, \[{{[FeHP{{O}_{4}}]}^{+}}\]with these acid and hence, the concentration of \[F{{e}^{3+}}\] ion reduces which results in lowering in the formal reduction potential.You need to login to perform this action.
