檢驗化學反應生成水無水金沙城线路检测中心:硫酸铜有極強的吸水性,無水金沙城线路检测中心:硫酸铜固體遇水由白色變藍色,生成五水金沙城线路检测中心:硫酸铜(CuSO4·5H2O),可檢驗化學反應水的存在或生成,并吸收水蒸汽。注:CuSO4與CuSO4·5H2O都是純淨物。化學方程式:CuSO4+5H2O==CuSO4·5H2O(反應條件:加熱)
Check that the anhydrous copper sulfate produced by chemical reaction has strong water absorption. When the anhydrous copper sulfate solid meets water, it changes from white to blue, and forms copper sulfate pentahydrate (CuSO4.5H2O). It can check the existence or formation of the chemical reaction water and absorb water vapor. Note: CuSO4 and CuSO4.5H_2O are pure substances. Chemical equation: CuSO4+5H2O==CuSO4.5H2O (reaction condition: heating)
