1.

The e.m.f. of the cell `Ti|Ti^(+)(0.001M)||Cu^(2+)(0.01M)|Cu` is 0.83V the emf of this cell could b e increased byA. increasing the concentration of `TI^(+)` ionsB. increasing the concentration of `Cu^(2+)` ionsC. increasing the concentration of bothD. none of above .

Answer» Correct Answer - B
Cell reaction `2 Tl + Cu^(2+) to 2 Tl^(+) + Cu`,
`E_("cell") = E_("cell")^(@) - (2.303 RT)/("nF") "log" ([Tl^(+)]^(2+))/([Cu^(2+)])`.
