Ph Of Battery Acid
Battery acid has a ph of approximately 0 8.
Ph of battery acid. When fully charged it is a strong acid. A typical car battery sliced open. When is electrolyte used. Usually the acid has a mole fraction of 29 32 sulfuric acid a density of 1 25 1 28 kg l and concentration of 4 2 5 mol l.
Car or automotive battery acid is 30 50 sulfuric acid h 2 so 4 in water. The electrolyte is usually used in the sealed lead acid battery. H concentration relative to pure water. But there is one more type in which the sulfuric acid is normally used.
On average a mole fraction of acid is 29 32 of sulfuric acid density is 1 25 1 28 kg l and concentration of 4 2 5 mol l a ph of battery acid is about 0 8. For example in the familiar 12 v lead acid battery used in automotive applications the ph level changes as the battery charges or discharges. To give you some comparison water has an acidity of 7 and battery acid is at a 1 on the ph scale. Some batteries use acid in a chemical reaction to produce electric current.
The acidity of your average candy of even the mildest of tangingess start around a 3 to a 2 5 of.
