We’re being asked to calculate the pH of a 0.044 M HI solution.
We can calculate pH using the following equation:
Take note that: [H+] = [H3O+]
HI is one of the strong binary acids. Since HI is a strong acid, it will completely dissociate in the solution:
HI(aq) → H+(aq) + I-(aq)
Given: [HI] = 0.044 M
Ratio: 1 mol of HI produces 1 mol of H+
What is the pH of a 0.044 M HI solution?
