(i) By the standa
(i) No Ti4 + cannot oxidize Fe(II) to Fe(III).
As it is clearly stated that Ti4 + has lower reduction potential ( + 0. 01V) than Fe3 + ( + 0. 77V). Ti4 + cannot get reduced as compared to Fe3 + . Therefore Ti4 + cannot oxidise Fe(II) to Fe(III).
(ii) Cr3 + /Cr2 + < Fe3 + /Fe2 + < Mn3 + /Mn2 +
As the value of reduction potential increases,the stability of the + 2 oxidation state also increases. Since, - 0. 4V<0. 8V<1. 5V
Cr3 + /Cr2 + < Fe3 + /Fe2 + < Mn3 + /Mn2 + .
