Calculate the ph of a solution that is 0.157m HCI?
0.804
You must have made a typo; is that 0.157 M?
If so then pH = -log(HCl) = ?
To calculate the pH of a solution, you need to know the concentration of hydronium ions (H3O+) in the solution. In the case of a strong acid like hydrochloric acid (HCl), the concentration of H3O+ ions is equal to the concentration of the acid.
Given that the concentration of HCl is 0.157 M, we can assume that the concentration of H3O+ ions is also 0.157 M.
The pH is then calculated using the formula:
pH = -log[H3O+]
Substituting the value:
pH = -log(0.157)
Using a scientific calculator, you can calculate the logarithm of 0.157 to find the pH value. Remember to use the negative sign before taking the logarithm.
Therefore, to find the pH of the 0.157 M HCl solution, calculate -log(0.157) using a calculator. The result will be the pH of the solution.
