I really have no idea. I'm trying to find out the same thing for a science project but so far no websites have lead me to the answer. No one seems to know.
When you add baking soda to buttermilk, the pH level increases. Baking soda is basic (alkaline), so it raises the pH of the acidic buttermilk. This reaction helps to neutralize the acid in the buttermilk.
According to a list compiled by the U.S. Food and Drug Administration's Center for Food Safety and Applied Nutrition, the pH of buttermilk ranges from 4.41 - 4.83. http://www.cfsan.fda.gov/~comm/lacf-phs.html
When you add buttermilk to baking soda, a chemical reaction occurs that produces carbon dioxide gas, causing the mixture to bubble and rise. This reaction also increases the pH of the mixture, making it more basic.
My guess, knowing something about the diary butter making process (charning acidified milk = buttermilk) is that the pH is somewhat lower than 5, not neutral anyhow, but slightly acid, though you can't taste it in the 15% water phase. pH in the 85% fat phase is not an issue because pH is defined for aquous solutions and acids do NOT ionise or protolyse in fat (hydrophobic). When butter becomes old and rancid the pH gets lower and is tastable!
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.

You can use powdered buttermilk in recipes by mixing it with water to create a buttermilk substitute. Just follow the instructions on the package to reconstitute the powdered buttermilk, and then use it in place of liquid buttermilk in your recipes.

Buttermilk was Dale Evans' horse.
Buttermilk - Le babeurre Lassi (indian drink meaning sweet buttermilk) - Le babeurre doux
Cultered buttermilk can be substituted by kefir.
Buttermilk falls is located in Owego, New York.
Buttermilk (gelding) was an American Quarter Horse.
You substitute the buttermilk for the water in the recipe. Measure the buttermilk and put in the freezer about an hour before mixing with the lye. If the buttermilk is not very cold, almost frozen, it will burn when mixed with the lye.
