There are several issues here however, besides the questionable quackwatch.
1) If you take vitamin C your urine will be more acidic than usual. Typically urine is mildly basic normally.

Acid/ base in the blood are very narrow. Typically the body can manage it.
However, simply hyperventilating will alter the pH of the blood temporarily.
Some drugs will elevate acid in the blood by blocking bicarb...like Topamax
and also metformin for diabetes.
Kidney issues, can raise acid in the blood too, tubular acidosis.
I don't believe that foods are a huge issue, or that the "drops" sold actually do anything. We need more research on that.
People do vary in saliva pH. My dentist told me that. One type makes alot of tartar on the teeth, the other doesn't.
