| Abstract: | The determination of chloride by n-octy1 alcohol as a protecant is used in Volhard's method, the result of which indicates that the method is more accurate and repeatable, and the end point is very sedative to changes in colour. And such poisonous substance as nitrohenzene is avoided to use. So the method can be used to determine chloride in practical work. |

| Keywords: | n-octyl alcohol nitroberzene back titration protectant |
