Is Soybean Oil Acidic or Alkaline?
Soybean oil (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Soybean oil is exactly neutral at 0.0. Pure fat contains no protein or phosphorus and no potassium, magnesium or calcium, the values the PRAL is calculated from. So frying with it doesn't change your acid balance; what matters is what's in the pan. At 900 kcal per 100 ml, though, it does move your calorie balance.
In the Oils & Fats category, soybean oil (raw) ranks #9 of 22, sorted from alkaline to acid-forming. More alkaline options include Sunflower oil (0.0), Sesame oil (−0.2), Margarine (−0.4). More acid-forming are Safflower oil (0.0), Coconut oil (0.0), Flaxseed oil (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 soybean oil 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: Soybean oil (raw) has a PRAL of 0.0 per 100 ml, so it counts as neutral in your daily acid-base balance.
Does soybean oil count in the acid-base balance at all?
Hardly. At 0.0 per 100 ml, soybean oil is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
