the ph of a solution is 2.0. which statement is correct? useful formulas include h₃o⁺=10⁻ᵖᴴ, oh⁻=10⁻ᵖᴼᴴ, ph + poh = 14, and h₃o⁺oh⁻=10⁻¹⁴. the poh of the solution is 12.0. the concentration of oh⁻ ions is 1.0×10⁻² m. the concentration of h₃o⁺ ions is 100.0 m. the poh of the solution is 16.0.

Answer

Explanation:

Step1: Calculate pOH

Given pH + pOH = 14, and pH = 2.0. So pOH=14 - pH. pOH = 14 - 2.0 = 12.0

Step2: Calculate [H₃O⁺]

Using the formula [H₃O⁺]=10⁻ᵖᴴ, with pH = 2.0, then [H₃O⁺]=10⁻² M = 0.01 M

Step3: Calculate [OH⁻]

Using the formula [OH⁻]=10⁻ᵖᴼᴴ, with pOH = 12.0, then [OH⁻]=10⁻¹² M

Answer:

The pOH of the solution is 12.0.
