The first row, labelled I, lists the Original ailments: the concentration of acid is C0, initially undissociated, And so the concentrations of A− and H+ could be zero; y is the First concentration of included solid acid, including hydrochloric acid. If powerful alkali, such as sodium hydroxide, is extra, then y can have a negative indicator since alkali gets rid of hydrogen ions through the solution.
