You are given 10.00 mL of a solution of an unknown acid. The pH of this solution is exactly 2.36. You determine that the concent
Harlamova29_29 [7]

Answer:

4.27

Explanation:

Let's consider the dissociation of a generic monoprotic acid.

HA(aq) → H⁺(aq) + A⁻(aq)

The pH is 2.36. The concentration of H⁺ is:

pH = -log [H⁺]

[H⁺] = antilog -pH

[H⁺] = antilog -2.36 = 4.37 × 10⁻³ M

We know that the concentration of the acid Ca = 0.3535 M. We can find the acid dissociation constant using the following expression.

[H⁺] = √(Ca × Ka)

Ka = [H⁺]²/Ca

Ka = (4.37 × 10⁻³)²/0.3535

Ka = 5.40 × 10⁻⁵

The pKa is:

pKa = -log Ka = -log 5.40 × 10⁻⁵ = 4.27
