Question #14369
1 Answer
The pH of the resulting solution will be 1.
So, you're mixing three hydrochloric acid solutions, each with a different molarity and volume. In order to get the pH of the resulting solution, you need to first determine what the molarity of the resulting solution will be.
Since molarity is defined as moles of solute per liters of solution, you can determine how many moles of
The total number of moles of hydrochloric acid will be
The total volume of the solution will be
This means that the molarity of the final solution will be
You know that
Because hydrochloric acid dissociates completely, the concentration of the
As a result, the pH of the solution will be
