    Answer:

    a. 1.0 × 10⁻⁶ M (≈ 10⁻⁶ M)

    Explanation:

    Step 1: Given data

    pOH of the solution: 6.0

    Step 2: Calculate the concentration of hydroxide ions ([OH⁻]) in the solution

    We will use the definition of pOH.

    pOH = -log [OH⁻]

    [OH⁻] = antilog -pOH

    [OH⁻] = antilog -6.0

    [OH⁻] = 1.0 × 10⁻⁶ M

    Since [OH⁻] > 10⁻⁷ M, we can conclude that the solution is basic.
