C) a voltaic cell consists of zn/zn2+ half-cell and a ni2+/ni half-cell at 25°c.
i. what is the initial concentration if the initial concentration of ni2+ and zn2+ are
1.75 m and 0.15 m, respectively?
ii. what is the cell potential when the concentration of ni2+ has fallen to 0.45 m?
ii.
what is the number mole of zn2+ in 500 ml solution if ecell is 0.6 v and [ni2+]
is 2.8 m
