An ion selective electrode used to measure Mn2+ is also sensitive to Li+ and obeys the equationE = constant + 57.1 mV/2 log{[Mn^2+] + 0.002[Li^+]2}When the electrode was immersed in 100.0 mL of unknown containing Mn^2+ in 0.200 M LiCI, the reading was 194.6 mV. When 1.00 mL of 1.07 X 10^-2 M Mn^2+ (in 0.2 00 M LiCI ) was added to the unknown, the reading increased to 200.7 mV. Find the concentration of Mn^2+ in the original unknown.
