    pOH = 4.8

    pH = 9.2

    Explanation:

    Given dа ta:

    Hydrogen ion concentration = 6.3*10⁻¹⁰M

    pH of solution = ?

    pOH of solution = ?

    Solution:

    Formula:

    pH = - log [H⁺]

    [H⁺] = Hydrogen ion concentration

    We will put the values in formula to calculate the pH.

    pH = - log [6.3*10⁻¹⁰]

    pH = 9.2

    To calculate the pOH:

    pH + pOH = 14

    We will rearrange this equation.

    pOH = 14 - pH

    now we will put the values of pH.

    pOH = 14 - 9.2

    pOH = 4.8
