The pH of the diluted HCl solution is 1.3.
Explanation:
Given:
The concentrated HCl solution of 8.0 M. The 1.5 mL of 8.0 M HCl is diluted with water to 250 mL volume.
To find:
The pH of the diluted HCl solution.
Solution
- The concentration of the HCl solution before dilution =
- The volume of the HCl solution taken for dilution =
- The concentration of the HCl solution after dilution =
- The volume of the HCl solution after dilution =
Using the Dilution equation:
The concentration of diluted HCl solution = 0.048 M
In the 1 M solution of HCl, there are 1 M of hydrogen ion, then the concentration of hydrogen ions in 0.048 M of HCl will be:
The pH of the diluted HCl solution :
The pH of the diluted HCl solution is 1.3.
