Explanation:
First, let's begin with some definitions:
- In the Bronsted-Lowry definition, acids are donors of
#H^+# ions. - Strong acids are those that almost completely ionise in aqueous solutions to form these
#H^+# ions. #pH# is the negative#log# of the concentration of hydrogen cations (#[H^+]# ) in an aqueous solution.
Let's plug some numbers in for
We can see that, as
As the
We defined a strong acid as one that almost completely ionises in aqueous solutions to form
Therefore, as the
