The pH of Baking soda (Sodium bicarbonate NaHCO3) in pure water is pH 8.2
See link below.
the pH of baking powder is 1 the highset
Baking powder is a base since its pH level is somewhere between 8 and 8.5.
10 to 11
No, at pH = 8 (tap water pH) no CaCO3 will precipitate at normal tap water temperature. pH of sodium bicarbonate (baking powder) is also 8.
Baking soda, also known as sodium bicarbonate, has a pH around 9, making it alkaline. It helps to neutralize acids and can be used in baking as a leavening agent.
As indigestion is caused by acid, the pH value is around 2-4.
Baking Powder
Baking powder in a recipe helps your item rise when baking.
baking powerder is baking powder is not the same!
baking powder
Baking Powder is a proprietary mixture of ingredients, including an alkaline (base) baking soda (base) and acid powder(s) like cream of tartar, MCP and SAS, and often a stabilizer like cornstarch (acid to neutral). Because the PH of a powder is measured when mixed with water, and usually one or more of the acids aren't soluble at room temperature, baking powder will turn from an alkaline to neutral when cooked with a liquid. This chemical reaction causes the release of CO2, which is why my bread has these little holes that makes it so fluffy.
Not sure what the question is asking.Baking soda cannot replace baking powder. Baking powder will raise a batter by itself; baking soda requires additional ingredients with which to react and raise the batter.For a homemade recipe for baking powder, see here: http://frugalliving.about.com/od/condimentsandspices/r/Baking_Powder.htmAn additional note: baking powder will go bad over time, so if your recipes are turning out flat instead of fluffy, try getting some new baking powder.
