What is the ph of a 0. 300 m solution of aniline (c₆h₅nh₂, kb = 4. 3 × 10⁻¹⁰)?.
yawa3891 [41]

The pH of the solution of aniline is; pH = 4.64

<h3>pH of aniline solution</h3>

According to the question;

  • We are required to determine the hydrogen ion concentration, pH of the given aniline solution.

Since, the given Kb is kb = 4. 3 × 10⁻¹⁰.

Hence, it follows that;

  • Ka = 10-¹⁴/4. 3 × 10⁻¹⁰.

  • Ka = 2.3 × 10⁻⁵.

On this note, the pH of aniline solution is;

  • pH = -log {2.3 × 10⁻⁵}

pH = 4.64.

Ultimately, the pH of the aniline solution given is; 4.64
