A bromine ion selective electrode has a selectivity coefficient K Br-, OH = 0.05. What will be the change (absolute value in mV, NO UNITS, one figure after decimal point examples 3.3 or 33.0) in electrode potential when in 4.0 x 10-5 M Br aqueous solution pH 6.0 is raised to pH 9.8 at constant temperature of 25 °C? Give answer as an absolute value in mV, NO UNITS, one figure after decimal point, examples 3.3 and 33.0 Answer:
