Answer:
The answer to your question is [H⁺] = 3.16 x 10⁻⁹ M
Explanation:
Data
[H⁺] = ?
pOH = 5.5
Process
Calculate the pH, after that calculate the [H⁺]
1.- Calculate the pH
pH + pOH = 14
-Solve for pH
pH = 14 - pOH
-Substitution
pH = 14 - 5.5
-Result
pH = 8.5
2.- Calculate the [H⁺]
Formula
pH = -log[H⁺]
-Substitution
8.5 = -log[H⁺]
-Solve for [H⁺]
[H⁺] = antilog(-8.5)
-Result
[H⁺] = 3.16 x 10⁻⁹ M
