Is Still Mineral Water Acidic or Alkaline?
Mineral water, still (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Still mineral water sits at −0.2 per 100 ml, just as close to zero as sparkling water, because carbonation doesn't count toward the balance. The small minus comes from dissolved calcium and magnesium. If you drink a lot, it still adds up a little: one and a half liters over the day add about −3.5.
In the Drinks category, still mineral water (raw) ranks #51 of 80, sorted from alkaline to acid-forming. More alkaline options include Cream liqueur (−0.2), Latte macchiato (with milk, 3.5%) (−0.3), Cappuccino (with milk, 3.5%) (−0.3). More acid-forming are Radler (beer with lemonade) (−0.2), Green tea (−0.2), Wheat beer (−0.2).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is still mineral water acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Mineral water, still (raw) has a PRAL of −0.2 per 100 ml, so it counts as neutral in your daily acid-base balance.
Does still mineral water count in the acid-base balance at all?
Hardly. At −0.2 per 100 ml, still mineral water is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
