The pH of car battery solution is approximately 0.8.
Car batteries contain a solution of sulfuric acid and water. The concentration of sulfuric acid typically ranges from 30% to 50% by weight, resulting in a strongly acidic environment. This high concentration of acid directly translates to a very low pH value.
Here's a breakdown of factors contributing to the pH:
- Sulfuric Acid Concentration: The higher the concentration of sulfuric acid (H₂SO₄), the lower the pH. The concentration in car batteries is significant.
- Mole Fraction: A mole fraction of 29% sulfuric acid also indicates a strong acid concentration.
- Density: The density of the solution, around 1.25 kilograms per liter, is a further indicator of the acid's concentration.
Because of the extremely corrosive nature of the sulfuric acid solution, appropriate safety measures such as wearing eye protection and gloves are essential when handling car batteries.
