How do you calculate the pH of a strong acid or base?
You calculate it normally -> find the concentration of the acid, transfer the concentration and insert the value in a logarithmic equation.
To calculate pH in general, you need the concentration of hydrogen ions in the compound.
Strong acids are acids with a pH of less than 4-ish while weak acids have a pH of 4-ish to 7.0.
In order to find mols, we typically use stoichiometry and the concentration formula
When you find concentration of an acid, you need to transfer the concentration to each individual element.
#H_"2"SO_"4" (aq) -> 2H^+ (aq) + SO_"4"^(2-) (aq)#
As a result, your hydrogen concentration is
Use the logarithm function to find pH:
#pH = -log [H^+]#
In this example, the pH of
