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;
On this note, the pH of aniline solution is;
pH = 4.64.
Ultimately, the pH of the aniline solution given is; 4.64

Let Z be a random variable following the standard normal distribution with mean µ = 0 and standard deviation σ = 1.
The 67th percentile of the distribution is the value z that separates the bottom 67% of the distribution from the top 100% - 67% = 33%. In terms of probability, we have
Pr[Z ≤ z] = 0.67
Use the inverse CDF for the normal distribution (or lookup z scores in a table) to find
z = ɸ⁻¹(0.67) ≈ 0.4399
where ɸ(z) is the CDF for the normal distribution.
