A strip of nickel metal is dipped in a 1 molar solution of Ni (NO_(3))_(2) and a strip of silver metal is dipped in a 1 molar solution of AgNO_(3) . An electrochemical cell is created when the two solutions are joined by salt bridge and two strips are joined by wire to a voltmeter. Answer the following questions. Calculate the cell potential (E_("cell")) at 25^(@)C for the cell if the initial concentration of Ni (NO_(3))_(2) , is 0.100 molar and the initial concentration of AgNO_(3) is 1.00 molar. [E_(Ni^(2+)//Ni)= -0.25V, E_("Ag^(+)//Ag)=0.80V, log 10^(-1)= -1]
