Full Answer

Car battery acid is a very volatile and dangerous substance. If you need to replace a car battery, make sure to wear the proper safety gloves and goggles. If the method to replace the battery is not known, seek the help of a professional mechanic. Do not dispose of the car battery with normal trash because the acid wreaks havoc in landfills and can potentially poison the water supply.

  • Q:

    What is the pKa of sulfuric acid?

    A:

    The pKa of sulfuric acid is -3. This value corresponds to a Ka of 1.0 x 10^3 as the pKa is the negative logarithm of the Ka value. Sulfuric acid is considered a strong acid because the Ka is larger than 1.

  • Q:

    What is the pH level of hydrochloric acid?

    A:

    The pH of hydrochloric acid is 0. This reading is taken from a solution of 1 mole of hydrochloric acid. A less concentrated solution of the acid, such as a 0.5-mole solution, has a higher pH, meaning it would be less acidic.
