a solution prepared by mixing 60ml of .1m agno3 and 60ml 0f .1m
tino3 was titrated with .2M nabr in a cell containing a silver
indicator electrode and a reference electrode of constant potential
.175 v. the reference electrode is attached to the positive
terminal of the potentiometer, and the silver electrode is attached
to the negative terminal. the solubility constant of tibr is
ksp=3.6x10^-6 and the solubility constant of agbr is
ksp=5x10^-13.
AgBr precipitates first
the following expression shows...
