Web- [Instructor] Here are some equations that are often used in pH calculations. For example, let's say a solution is formed at 25 degrees Celsius and the solution has a pOH of 4.75, and our goal is to calculate the concentration of hydronium ions in solution, H3O+. One way to start this problem is to use this equation, pH plus pOH is equal to 14.00. island360WebMay 6, 2024 · Kb = 10−pKb = 10−3.66 = [H 3CN H + 3][H O−] [H 3CN H 2]. Now if initially, [H 3CN H 2] = 0.470 ⋅ mol ⋅ L−1, and we say the amount of dissociation is x, then we can write: Kb = [H 3CN H + 3][H O−] [H 3CN H 2] = (x) × (x) 0.470 −x = x2 0.470 −x = 10−3.66.
