Establish the Ka expression of the dissolution of trimethylammonium bromide (CH3)3NHBr 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 (CH3)3NHBr
Step 2: Write an expression for the Ka
Step 3: Set up an ICE table to calculate the H3O+ ion concentration.
What is the pH of 0.26 M trimethylammonium bromide, (CH3)3NHBr? Enter your answer with two decimal places.
The Kb of trimethylamine, (CH3)3N, is 6.3 x 10-5.
