Question

If the [–OH] concentration in a bottle of Windex is 9.8 x 10^(–6) M, what is its pH and pOH and is it acidic, basic or neutral? *

Answer 1

pOH = 5

pH = 9 → Solution is basic

Step-by-step explanation:

We need to know that:

pH + pOH = 14

< 7 ⇔ pH = 7 ⇔ > 7

Acidic Neutral Basic

pOH = - log [OH⁻] → - log 9.8×10⁻⁶ = 5.00

pOH = 5

pH = 14 - 5 = 9
