某反应物与另一反应混合物中的几种成分都能发生反应,就存在反应先后的顺序问题,产物的量则由后发生的反应来决定。本文举例对比说明如下。一、计算顺序与反应顺序相同对于一些平行反应,不同产物的生成顺序与反应顺序一致,产物的计算顺序与反应顺序也相同。例1溶液中c(Al~(3+))=1mol/L,c(NH~+_4)=2 mol/L,若取该溶液100mL,当加入1 mol/L NaOH__mL时,沉淀量不再增加。当又加入
A reactant with another reaction mixture of several components can react, there is the order of reaction problems, the amount of product by the reaction to decide. This article illustrates the contrast as follows. First, the order of calculation and the same order of reaction For some parallel reactions, the order of formation of different products is consistent with the order of reaction, and the calculation order and reaction order of the products are also the same. In the solution of Example 1, when the concentration of c (Al 3+) = 1mol / L and c (NH + 4) = 2mol / L, increase. When added again
