the poh of a solution is 6.0. which statement is correct? use poh = -logoh- and ph + poh = 14. the ph of the solution is 20.0. the concentration of oh- ions is 1.0 x 10^-8 m. the concentration of oh- ions is 1.0 x 10^6 m. the ph of the solution is 8.0.

the poh of a solution is 6.0. which statement is correct? use poh = -logoh- and ph + poh = 14. the ph of the solution is 20.0. the concentration of oh- ions is 1.0 x 10^-8 m. the concentration of oh- ions is 1.0 x 10^6 m. the ph of the solution is 8.0.

Answer

Explanation:

Step1: Calculate the pH

Given pH + pOH = 14, and pOH = 6.0. Then pH=14 - pOH. pH = 14 - 6.0 = 8.0

Step2: Calculate the concentration of OH⁻ ions

Given pOH = -log[OH⁻], and pOH = 6.0. Then [OH⁻]=10^(-pOH). [OH⁻]=10^(-6.0)=1.0×10⁻⁶ M

Answer:

The pH of the solution is 8.0.
