    Answer: 1.0 x 10^-3M

    Explanation:

    The solution with pH 3 is said to be acidic because pH values less than 7 are regarded as acidic, and will produce hydrogen ions.

    Mathematically, pH is expressed as

    pH = - log (H+)

    where H + is the concentration of hydrogen ion

    So, pH calculations are as follows

    3 = - log (H+)

    (H+) = Antilog (-3)

    (H+) = 0.001M

    Place (H+) in standard form

    (H+) = 1.0 x 10^-3M

    Thus, the value of hydrogen ion (H+) in the solution with pH 3 is 1.0 x 10^-3M
