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 1.0×10⁻² m. the concentration of oh⁻ ions is 1.0×10⁶ 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 1.0×10⁻² m. the concentration of oh⁻ ions is 1.0×10⁶ m. the ph of the solution is 8.0.

Answer

Explanation:

Step1: Calculate the pH value

Given pH + pOH = 14, and pOH = 6.0. Then pH=14 - pOH. Substitute pOH = 6.0 into the formula: pH = 14 - 6.0 = 8.0.

Step2: Calculate the concentration of OH⁻ ions

Given pOH=-log[OH⁻], and pOH = 6.0. Then -log[OH⁻]=6.0, which can be rewritten as [OH⁻]=10⁻⁶.⁰ M = 1.0×10⁻⁶ M.

Answer:

The pH of the solution is 8.0.
