【Abstract】 In the presence of methanol, the mixture of Ca(OH) 2 and CaCO 3 can be analyzed with high accuracy and precision by EDTA complexometry. CaCO 3 does not interfere the titration of Ca(OH) 2,if the volume ratio of methanol to water is larger than 0 2. Between the region of 0 2 to 0 6 of the volume ratio, Ca(OH) 2 can be titrated accurately and precisely. The analytical procedure and the statistical processing of the analytical data have been discussed in detail. This analytical method has been used to inspect the whole carbonation process of the lime milk successfully.更多还原
