<u>Answer:</u> The hydronium ion concentration in the solution is
<u>Explanation:</u>
To calculate the molarity, we use the equation:
Moles hydrochloric acid solution = 0.060 mol
Volume of solution = 1 L
Putting values in above equation, we get:
The chemical reaction for aniline and HCl follows the equation:
<u>Initial:</u> 0.24 0.060 0.31
<u>Final:</u> 0.18 - 0.37
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
We are given:
= negative logarithm of acid dissociation constant of benzoic acid = 4.2
pH = ?
Putting values in equation 1, we get:
To calculate the hydronium ion concentration in the solution, we use the equation:
pH = 3.89
Putting values in above equation, we get:
Hence, the hydronium ion concentration in the solution is
