Is Celeriac Acidic or Alkaline?
Celeriac (fresh) is strongly alkaline: Negative PRAL: alkalizing after digestion.
Classification
Celeriac is clearly alkaline at −8.3, because the root contains plenty of potassium with little protein and is very light at 30 kcal per 100 g. As a purée, a soup or a breaded, pan-fried schnitzel, you can eat it in larger amounts than typical soup greens. A purée of half celeriac and half potato makes a side dish that offsets acid-forming meat well.
In the Vegetables & Salad category, celeriac (fresh) ranks #12 of 110, sorted from alkaline to acid-forming. More alkaline options include Lamb's lettuce (−8.3), Potato, with skin (−8.7), Chicory (−9.3). More acid-forming are Swiss chard (−7.8), Horseradish (−7.6), Arugula (−7.1).
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 celeriac 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: Celeriac (fresh) has a PRAL of −8.3 per 100 g, so it counts as strongly alkaline in your daily acid-base balance.
How much celeriac do I need for a noticeable effect?
A serving (150 g) of celeriac adds −12.4 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of celeriac roughly offsets one of them.
Why is celeriac alkaline even though it is not a typical alkaline food?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Celeriac provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−8.3).
