Acidic: Normally urine PH should be acidic (6.8) to prevent infection. Vitamin C is an acidic food but I am not sure if this plays enough role to increase or decrease the PH. Please see a doctor.

Acid: 80% of uncomplicated UTIs are due to E.coli.Urine has nitrates(from diet &produced naturally in body).Bacteria with nitrate reductase activity(eg:E.coli)convert nitrates to nitrites.At acid ph(low,eg:5-5)nitrites are converted to nitric oxides which are toxic to bacteria.So Vit.C(ascorbic acid)lowers ph.Dose is 75mg daily for female,90mg.for male.No space to discuss other type of UTIs.
