What is an example of a pH practice problem?
Generally, most pH problems ask you to determine pH from
Let's look at the strong acid HCl, hydrochloride acid, which has a concentration of 0.1 molar.
In aqueous solutions, hydrochloric acid dissociates into hydrogen and chloride ions.
Because there is a one to one ratio between the acid and the hydrogen ion, the
Now convert the hydrogen ion concentration to pH using the equation pH = -log
Applying this to our problem
pH = -log
pH = -log [0.1]
pH = 1
To reverse the problem from pH to [H+]
Use the equation
[H+] = antilog(-pH)
