Possibly in times of extreme blood acidity the kidneys will add ammonium 
ions (or if blood is too acid, hydrogen [from phosphorus - from bone if 
otherwise unavailable]). See Phil's excerpt below from one of his earlier 
messages:

Acid-Alkaline Balance and Your Health

"The kidney also responds to the pH of the blood. If the blood is too acid,
the kidney excretes extra hydrogens into the urine and retains extra sodium.
Phosphorus in the form of phosphate is required for this exchange. The body
obtains this phosphorus from bone if it is otherwise unavailable. When the
bloodstream is extremely acid, the kidney uses a different method and
excretes ammonium ions, which contain four hydrogens, into the urine. When
the body is too alkaline, the process is reversed, and hydrogen is
retained."
