    For this problem you need to know the acidity constant for citric acid. This is generally represented by the formula
    Ka = [hydrogen ions][acid ions] / [acid]
    It expresses the ratio of hydrogen ions and acid ions to acid in solution. For citric acid, it is 7.41 x 10^-4.

    Next, it's important to know what type of acid you're dealing with. When calculating the pH of a ...
