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.
