But sir, I don't want to DRINK my AP water...Originally Posted by rfeiller
Aren't you using RO water? How would you get acids/bases with their conjugates in the water... You have ammonia in the water, but at a very low molar density... Also, you are discussing strong and weak acids, but you don't seem to draw a distinction between the two. You realize they act differently in solutions with or without a buffering solution present, yes?
Here are some good videos on buffer calculations:

There are many things to consider in the interactions, and without specifics we can't really say for certain. However, it's not magic; there is sound science from which to base our decisions... pH interactions are probably one of the simplest (yet the most important) aspects of our AP systems...
