(1) Do not contact concentrated sulfuric acid and crystalline potassium permanganate;

(2) Do not grind potassium chlorate together with organic matter;

(3) Do not grind salt with organic matter. Organics must not be mixed with concentrated nitric acid and heated.


5. Copper acetylene, silver acetylene powder most likely to explode, so when the test is completed, it and the solution fell to the outdoors with the soil buried.


6. Use ether, the first method should be checked for the presence of peroxide ether: Take 10 ml of ether into the test tube, add 10 ml of freshly prepared 10% potassium iodide solution 1 ml, shake for 1 minute, such as the ether layer was yellow, you can not use This ether.
