Question
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
O 0.0050
O 0.123
