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___________

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___________
