Morning folks.
As I mentioned yesterday, this is complex (!), and probably solved by trial and error lab work, not theoretically.
The baffling thing, is that one of the solutions, normally K+ ions is the culprit in this case. K in the mud often tames sticky clays but in this case K in the clay is reacting with the mud.
I had wondered if Na, or Ca could replace K in the mud lattice, but K has the most powerful effect.
I’m a bit baffled.
