Calculate the pH of a 0.30 M solution of ammonia (NH3, Kb = 1.8 x 10-5.)

a. 11.37

b. 10.57

c. 8.88

d. 3.43

e. 2.63


Establish the Kb expression of the dissolution of ammonia (NH3) and determine the pH using an ICE chart

We will solve this problem through these steps:

Step 1: Write an equation for the dissociation of NH3

Step 2: Write an expression for the Kb

Step 3: Set up an ICE table to calculate the OHion concentration.
