| Abstract: | The article discussed the changing relation between total alkalinity content and titration equivalence point and changed situation of methyl orange in the different PH value color. Ittried the common 10 kinds of acid - base indicators which are available in the titration water sample total alk alinity. The result indicated that the end point of bromocresol green indicator is advantageous and shows clearly color. |
