Calculate the ph of a 0.239 mol HCL solution
To calculate the pH of a hydrochloric acid (HCl) solution, we need to first determine the concentration of HCl in the solution and then use the formula for pH.
Given:
Moles of HCl = 0.239 mol
Volume of solution = 1 L (Assuming)
Concentration of HCl = Moles/Volume
Concentration = 0.239 mol / 1 L = 0.239 M
Now, to calculate the pH, we use the formula:
pH = -log[H+]
[H+] represents the concentration of hydrogen ions in the solution, which in this case is equal to the concentration of HCl (0.239 M).
pH = -log(0.239) ≈ -log(2.39 x 10^-1) ≈ -(-0.620) ≈ 0.620
Therefore, the pH of a 0.239 M HCl solution is approximately 0.620.
