DETERMINATION OF PERCENT KHP AND ACID EQUIVALENT WEIGHT

DETERMINATION OF PERCENT KHP AND ACID EQUIVALENT WEIGHT Titration is a process of mixing measured volumes of reacting solutions in such a manner that one can determine when chemically equivalent amounts of reactants are mixed. One of the purposes of the titration process is to determine the concentration of a solute in a solution. Additionally,
