What is the pH of a 0.35 M solution of a Base with a Kb = 4.4 × 10–4 at 25oC? Identify the step(s) where a mistake was made. Step 1: An ICE table was set up Step 2: The student ran the 5% test and it failed. Step 3: At equilibrium, the concentrations were the following: i. B= 0.35-x ii. Conjugate acid= x iii. Conjugate base= x Step 4: The value of x is equivalent to the pH. The step(s) that are incorrect is/are (if multiple steps,____________ use a comma to separate the steps) and the correct answer is___________
