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 1.0×10⁻⁸ 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 1.0×10⁻⁸ m. the concentration of oh⁻ ions is 1.0×10⁶ m. the ph of the solution is 8.0.

Answer

Explanation:

Step1: Calculate pH

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

Step2: Calculate [OH⁻] concentration

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.
