What is the pH of a solution that has a hydroxide ion concentration of 1.0×10−9 M?

bogdanovich [222]

Answer:

$\boxed{\text{pH = 5.00}}$

Explanation:

Step 1. Calculate the pOH

pOH =-log[OH⁻]

pOH =-log(1.0 × 10⁻⁹)

pOH = 9.00

Step 2. Calculate the pH

pH + pOH = 14.00

pH + 9.00 = 14.00

$\boxed{\textbf{pH = 5.00}}$
