Photography is full of chemistry, and the best I can say is that there is a lot of bad or approximate information out there.

This should be corrected to read:

"Positive charge does go down as pH goes up and negative charge goes down as pH goes down. But, as pH goes up, swell goes up and as pH goes down, swell goes down. As swell goes down, diffusion goes down.

This should clarify my quoted post.
