calculate for strong electrolyte the ph of 0,1M pf HNO3
Please rephrase this question so it makes sense.
To calculate the pH of a strong electrolyte, like HNO3, you need to determine the concentration of the hydrogen ions (H+) in the solution.
In the case of HNO3, it is a strong acid and ionizes completely in water. So, one HNO3 molecule will dissociate into one H+ ion and one NO3- ion.
Given that the concentration of HNO3 is 0.1 M, the concentration of H+ ions in the solution will also be 0.1 M.
Now, to calculate the pH, you can use the formula:
pH = -log[H+]
Substituting the concentration of H+ ions:
pH = -log(0.1) = 1
Therefore, the pH of a 0.1 M HNO3 solution is 1.
Note that because HNO3 is a strong acid, it will dissociate completely, so the concentration of H+ ions will be equal to the initial concentration of HNO3. However, for weak acids or bases, additional steps are required to calculate the pH.
