Answer:
Ka = 1.14x10⁻⁸
Explanation:
First we <u>calculate [H⁺] from the pH</u>:
- pH = -log[H⁺]
- [H⁺] =
- [H⁺] = 6.31x10⁻⁵ M
For a monoprotic weak acid, the molar concentration of H⁺ of a solution can be expressed as:
- [H⁺] = √(C*Ka)
Where C is the molar concentration of the weak acid solution.
- 6.31x10⁻⁵ M =
- 1.14x10⁻⁸ = Ka
