硫酸-过氧化氢
(时间约3h),稍冷后加10滴H2O2(注1),摇匀,再加热至微沸(注2),消煮约5min,取下稍冷后,重复加H2O2 5-10滴,再消煮。如此重复3-5次,每次添加的H2O2的量应逐次减少,消煮到溶液呈无色或清亮后(应该为水的颜色),再加热约5-10min,以除尽剩余的H2O2。将消煮管取下,冷却。并用少...
过氧化氢俗称双氧水.可用过氧化钡与稀硫酸反应来制备.过氧化氢与过氧化钡都是过氧化物.过氧化物一般可用作氧化剂.漂白剂.供氧剂等.阅读下文并回答有关问题:与稀硫酸发生反应的化学方程式是BaO2+H2SO4═BaSO4+H2O2BaO2+H2SO4═BaSO4+H2O2.过氧化钡还可以通过以下方式制备
消煮到溶液呈无色或清亮后(应该为水的颜色),再加热约5-10min,以除尽剩余的H2O2。
