Principle total acid is determined determined 3ith a phenophthalein phenophthalein titration. Then HCl is determined determined 4, titrating Cl 3ith the the Mohr method. ntermediate calclations are sed to determine H since part of the Cl is tied p as ammonim salt. +asicall, the HCl is s4tracted from the total acid to determine the remaining acid6 3hich in this case is H.
