Problem 14-59

c. The [H⁺] concentration coming from the HCl is 1.0×10^-11 which is 10000 less concentrated than the one coming from the "natural" ionization of the water ([H⁺]_water = 1.00×10^-7). In other word, it will change nothing since there is not enough acid added to change the pH.
"The pH of the ocean cannot be changed by one drop of acid"
