A Br selective electrode is applied for measuring bromide ions in saline solution. Cl ions were found to interfere, with a kpot = 0.0050 %3D After calibration, the ISE equation was determined to be y = -70 mV - 59.2mV*log(x). If we measure a potential of 93 mV, and the [CI]=0.100 M, what was the [Br] in units of M? O 0.00821 O 0.100
