WebMar 6, 2024 · Explanation: First, let us generate the dissociation equation. This is illustrated below: HCl <==> H^+ + Cl^- From the equation, 1mole of HCl produced 1mole of H^+. This means that 6.2 x 10^-5M will also produce 6.2 x 10^-5M of H^+. Now we can calculate the pH of the solution as follows: [H^+] = 6.2 x 10^-5M pH = —Log [H^+] PH = —Log 6.2 x 10^-5 Web6th Sep, 2024. Paul Milham. Western Sydney University.
