Problem: Find the pH of a 0.130 M solution of a weak monoprotic acid having Ka = 1.6×10−5.

FREE Expert Solution

Establish the Ka expression of the dissolution of a weak acid HA 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 HA

Step 2: Write an expression for the Ka.

Step 3: Set up an ICE table to calculate the H3O+ ion concentration.
