    Answer:

    [H⁺] = 6.17×10¯⁶ M

    Explanation:

    From the question given above, the following data were obtained:

    pH = 5.21

    Concentration of Hydrogen ion [H⁺] =?

    The pH of a solution is defined by the following equation:

    pH = –Log [H⁺]

    With the above formula, we can obtain the concentration of Hydrogen ion [H⁺] in the solution as follow:

    pH = –Log [H⁺]

    5.21 = –Log [H⁺]

    Divide both side by –1

    –5.21 = Log [H⁺]

    Take the antilog of –5.21

    [H⁺] = Antilog (–5.21)

    [H⁺] = 6.17×10¯⁶ M

    Therefore, the concentration of Hydrogen ion [H⁺] in the solution is 6.17×10¯⁶ M
