Is Glucose (Dextrose) Acidic or Alkaline?
Glucose (dextrose) (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Dextrose is at −0.1 and neutral. Pure glucose contains no protein or phosphorus and no potassium or magnesium, so there is nothing to balance. Stevia is just as close to zero at +0.1. So the PRAL tells you nothing about sugar: the 399 kcal per 100 g remain, however neutral the mineral balance turns out.
In the Sugar & Sweeteners category, glucose (dextrose) (raw) ranks #5 of 12, sorted from alkaline to acid-forming. More alkaline options include Honey (−1.2), Brown sugar (−2.1), Maple syrup (−6.2). More acid-forming are Table sugar (0.0), Powdered sugar (0.0), Fructose (0.0).
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 glucose (dextrose) 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: Glucose (dextrose) (raw) has a PRAL of −0.1 per 100 g, so it counts as neutral in your daily acid-base balance.
Does glucose (dextrose) count in the acid-base balance at all?
Hardly. At −0.1 per 100 g, glucose (dextrose) is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
