Calculate the pH of a 0.15 M solution of formic acid (HCHO2). The Ka of formic acid is 1.8 X 10 -4
Formic acid (HCOOH) is a weak acid that partially dissociates as follows, with a Ka = 1.78Ã10-4: HCOOH + H2O â H3O+ + HCOOâ Calculate the [H+] and pH of a 0.646 M solution of formic acid. [H+]=______________
pH=________________
Now calculate the [H+] and pH of a 6.22Ã10-3 M solution of formic acid. [H+]=________________
pH=_________________
