Maybe I am looking too far into this question, but how does consuming a moderate amount of water push urine pH towards the alkaline end of the spectrum?

Thanks guys

My guess would be by dilution of protons, at least compared to a hypovolemic state but that's just off the tip of my head, perhaps there is a better explanation...

The ammonia(NH3 which deaminates for form urea) molecule reacts spontaneously with H2O to form ammonium and hydroxyl ions, which in turn alkalinizes urine by reducing hydrogen ion concentration.

Yeah remeber that from BIOCHEM circa'99:cool:

god i forget basic chem so pardon my ignorance here
but aren't highly polar molecules acidic?

i know water dissolves polar molecules thus neutralizing the acidity.

lol something like that ?
