We’re being asked to calculate the pH in each of the given solutions. We can calculate the pH using the following equation:
Take note that: [H+] = [H3O+]
• 3.6×10−2 M HI
• HI is one of the strong binary acids
• strong acid → completely dissociate in the solution:
HI(aq) → H+(aq) + I-(aq)
Given: [HI] = 3.6×10−2 M
Ratio: 1 mol of HI produces 1 mol of H+
Determine the pH of each of the following solutions., 3.6×10−2 M HI, 9.23×10−2 M HClO4, a solution that is 4.0×10−2 M in HClO4 and 4.8×10−2 M in HCl, a solution that is 1.01% HCl by mass (Assume a density of 1.01 g/mL for the solution.)
