盐酸滴定碳酸钠第二化学计量点碳酸浓度的探讨

DISCUSSION ON THE CARBONIC ACID'S CONCENTRATION OF THE SECOND CHEMICAL METERAGE POINT IN THE PROCESS OF TITRATING SODIUM CARBONATE WITH HYDROCHLORIC ACID

盐酸滴定碳酸钠第二化学计量点碳酸的浓度是溶液的pH值的计算依据,碳酸的浓度应该根据等物质的量反应原理,利用反应溶液的浓度具体计算得出,同时,应该明确说明计算时忽略碳酸的分解这一前提条件。

pH value of the solution is based on the carbonic acid's concentration at the second chemical meterage point in the process of titrating sodium carbonate with hydrochloric acid. The carbonic acid's concentration should be caculated with the concentration of the reacting solutions, and it should be emphasized that carbonic acid was without being decomposed.
