Now, as for practicality, since Potassium Nitrate is forming during precipitation, this changes the ionic strength and therefore the actual concentration and flow rate of the salt have to be adjusted to account for this very real change that is taking place. Usually, the salt is about 5% - 10% more concentrated and the salt flow rate is slightly lower than the silver rate to start, and ramps up ever so slightly so that the overall ionic strength change is compensated for. Go figure that one out.

Have fun with Nernst and Debye Huckle this evening.
