Solution: A voltaic cell is constructed froman Ni2 + (aq) - Ni(s) half-cell andan Ag+ (aq) - Ag(s) half-cell.The initial concentration of Ni2 + (aq) in the Ni2 + - Ni half-cell is [Ni2 + ] = 1.50×10−2 M

Problem

A voltaic cell is constructed from
an Ni2 + (aq) - Ni(s) half-cell and
an Ag+ (aq) - Ag(s) half-cell.
The initial concentration of Ni2 + (aq) in the Ni2 + - Ni half-cell is [Ni2 + ] = 1.50×10−2 M . The initial cell voltage is +1.13 V .

Will the concentration of Ni2 + (aq) increase or decrease as the cell operates?
