Temat postu: Potassium permanganate events
Potassium permanganate events
Dilute hydrochloric acid a few days before doing the experiment with copper oxide , and did not succeed,
christian louboutin pas cher
, so I tried to mentor heated copper oxide . Yesterday, when I take the tube , the tube at the bottom of the black stuff , my head look rusted , and that it is copper oxide , so the direct addition of hydrochloric acid, did not expect dramatic responses in a test tube up, I came to understand the test tube is Potassium permanganate . Soon , the whole lab has an irritating smell spread out , I do not react, the students have covered his nose. After the reaction was over, opened the front door, I quickly opened the window , then ran out to discard things . Bad smell for a long time have not disappeared . I subconsciously say one thing: So I have peace of mind to continue to do experiments. After returning home, I check the internet a bit , the reaction of the pungent odor of chlorine . I winced - chlorine ? It is toxic , but ah ! We are not poisoned , right? My mother smiled and said, silly , should I have to take you all go to the hospital to check ah. Said the mother. I fear the impact of the brain quickly , we will not ~ it? Such sentiments haunt me for a long time , then I think, even if there is toxic , it should also be a certain amount of intake , the amount should be fine with so little , and finally I took a little disturbed sleep. Today, the rain, but we all jump , maybe really all right . Potassium permanganate to this event being put down .
