What is the H+ concentration for an aqueous solution with pOH = 4.34 at 25 ∘C? Express your answer to two significant figures and include the appropriate units. View Available Hint(s)

Answer :

Answer: The concentration of hydrogen ions in the solution is [tex]2.19\times 10^{-10}M[/tex]

Explanation:

We are given:

pOH of the solution = 4.34

To calculate the hydrogen ion concentration, we first calculate pH of the solution, which is:

pH + pOH = 14

pH = 14 - 4.34 = 9.66

To calculate the pH of the solution, we use the equation:

[tex]pH=-\log[H^+][/tex]

We are given:

pH = 9.66

Putting values in above equation, we get:

[tex]9.66=-\log[H^+][/tex]

[tex][H^+]=10^{-9.66}=2.19\times 10^{-10}M[/tex]

Hence, the concentration of hydrogen ions in the solution is [tex]2.19\times 10^{-10}M[/tex]
