1 calculate the standard reaction potential (E) of the following cells.
(I) Fe2+ + Ag+ _ Fe3+ + Ag
(ii) Cd2+ + V _ CD + V2+
2. The CN- concentration of 20ml of a NaCN solution was determined by titration. The endpoint was reached after 300seconds with a current of 16.5mA. The H+ ion is generated by the reaction
2H2O _ O2 + 4H+ 4e-
Na+ + CN- + H+ + e- _ Na + HCNo
calculate the number of grams of Navan per litre of solution .
