The pH of a solution is calculated using the formula:pH = -log10[H+]where [H+] is the hydrogen ion concentration.Given the hydrogen ion concentration of 1.5 x 10^-6 M, we can calculate the pH as follows:pH = -log10 1.5 x 10^-6 Using a calculator, we find that:pH 5.82So, the pH value of the solution is approximately 5.82.
