| Abstract: | Indicator selection of is very important in titration.The precision and accuracy of the analytical results are affected by indicator.In this paper,both CMP mixed indicator and K-B miced indicator are elected for the titration of calcium with EDTA.Both the indicators are used to determine of Calcium in potash calcium fertilizer. These results are shown that the precision and accuracy of analytical results possesses good enough for chemical analysis. |
