Experiment of Quantitative Analysis is a course on quantitative chemical analysis, refer to analytical chemistry basic operation, analytical chemistry basic method and its application on above-mentioned fields. The experiment content includes acid-base titration(Determination of unknown base、Determination of organic acid molar mass),complex titration (Determination of aluminum by back titration、Determination of copper by replacement titration),redox titration (Determination of iron by potassium dichromate method,Determination of calcium by potassium permanganate method and Determination of copper by iodometric method),The experiment type includes verification type、comprehensive type and design type(Determination of calcium and barium in mixed solution、chromium waste water processed and chemical valence analysis).
Chemistry
“化学”一词,若单从字面解释就是“变化的学问”之意。化学是一门研究物质的性质、组成、结构、以及变化规律的基础自然科学。化学研究的对象涉及物质之间的相互关系,或物质和能量之间的关联。传统的化学常常都是关于两种物质接触、变化,即化学反应,又或者是一种物质变成另一种物质的过程。
