    Of the following given choices;

    A. Battery acid with a pH of 0.8

    B. Human saliva with a pH of 6.5

    C. Baking soda solution with a pH of 8.0

    D. Distilled water with a pH of 7.0

    The answer is; A

    This is because the pH of battery acid is lower than that of orange juice. The lower the pH, the higher its acidity. Properties of acids are that they have a sour taste to the tongue and are corrosive. A pH of above 7.0 means the substance is basic.
