    pOH = 11.65

    The pH of solution is 2.35

    Explanation:

    Given dа ta:

    Concentration of HBr = 4.5*10⁻³ M

    pH of solution = ?

    Solution:

    pH = - log[H⁺]

    pH = - log [4.5*10⁻³]

    pH = 2.35

    The pH of solution is 2.35.

    pOH of solution:

    14 = pH + pOH

    14 = 2.35 + pOH

    pOH = 14 - 2.35

    pOH = 11.65
