Question 3 (4 points) The concentration of hydroxide ions in a solution that has a poH of 6.0 is
a
10-6 M.
Ob
106 M.
Ос
101 M.
Od
10-8 M.

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.
