Question

Calculate the [H₃O⁺] of a solution with pOH = 12.16. (do not use scientific notation for your answer)

[H₃O⁺] =  

Answer 1

Answer 2

To calculate the concentration of hydronium ions ([H₃O⁺]) in a solution with a given pOH, we can use the relationship between pH, pOH, and the ion concentrations:

pH + pOH = 14

Given pOH = 12.16, we can find the pH:

pH = 14 - pOH pH = 14 - 12.16 pH = 1.84

Now that we have the pH, we can calculate the concentration of hydronium ions using the formula:

[H₃O⁺] = 10^(-pH)

[H₃O⁺] = 10^(-1.84)

Now, let's calculate the value:

[H₃O⁺] ≈ 0.014125

Therefore, the concentration of hydronium ions ([H₃O⁺]) in the solution is approximately 0.014125 M.
