ACIDS & BASES PROBLEM
ANSWER
 

Exercise

  Consider a base B with Kb = 1.8 x 10-5. Calculate the pH of a 2.47-M solution of B. Calculate the pH of a 2.47-M solution of BH+.

 

Answer

 

The pH of a 2.47-M solution of B is 11.82

The pH of a 2.47-M solution of BH+ is 4.43

 

Explanation

 
  1. This problem requires the use of ICE.
  2. Since the pH is given, [H3O+] can be determined and is equal to [A-].
