1 SO2 具有漂白性是因为SO2与反映物质结合生成了不稳定的无色物质，加热就能恢复原色。CL2和SO2的混合气体通入水中，漂白性消失 原因如下 Cl2+SO2+2H2O=H2SO4+2HCl2 NaHSO4+BaCl2=NACl+HCl+BaSO43 不行，空气中存在水和CO2等酸性气体，氨气极易溶于水，同时也会和酸性气体反应，从而降低制冷效果4 投入到浓硫酸，蓝色晶体变为无色，原因浓硫酸的吸水性，五水硫酸铜晶体变成了硫酸铜晶体。 投入稀硫酸，变成蓝色溶液，原因污水硫酸铜晶体溶于酸 可以 因为Al 在浓硫酸中钝化，不与浓硫酸反应5 硫酸根，溶液加硝酸酸化，在滴加BaCl2溶液，若产生白色沉淀，说明有硫酸根 氯离子，溶液加硝酸酸化，在滴加AgNO3溶液，若产生白色沉淀，说明含氯离子 铵根离子，溶液加碱，微热，试管口放置红色石蕊试纸，若变蓝，说明含氨根离子6 SO2+NaSiO3+H2O=NaSO3+H2SIO3↓ 又因为硅酸不溶于水，所以看到沉淀
