1:1  05-03[理·化学]周老师教大家判断溶液的酸碱性
推荐理由：当由水电离出的c(H+)<10-7mol/L时，溶液呈酸性？碱性？or中性？周老师教你快速判断。 讲解人：周业虹，北京市东城区中学教研室主任，北京市化学特级教师。 题面：在下列溶液中，能大量共存的一组离子是（ ） A． pH＝1的溶液中：NH4+、Fe2+、SO42-、Cl- B．通入过量SO2气体的溶液中：Fe3+、NO3-、Ba2+、H+ C． c(Al3+)＝0.1 mol/L的溶液中：Na+、K+、AlO2-、SO42- D．由水电离出的c(H+)＝1×10-13mol/L的溶液中：Na+、HCO3-、Cl-、Br- 【答案及详解】 本部分内容设定了隐藏,需要回复后才能看到
互动：同学你学会了吗？当由水电离出的c(OH-)<10-7mol/L时，溶液呈酸性？碱性？or中性？
