The utility model discloses a reaction demonstration device for copper and dilute nitric acid, and aims for solving problems of complex assembly, and operation difficulty of a closed type nitric oxide preparing teaching experiment device in the prior art. The reaction demonstration device includes a ...
Would silver react with dilute hydrochloric acid? Why or why not? What observations do you see when hydrochloric acid and zinc are combined? Explain why a styrofoam cup is used as a calorimeter and not another material, such as a tin cup. ...
(b) metallic copper is added to a dilute solution of nitric acid,gaseous nitrogen(II) oxide is evolved and the solution becames a pale blue(c) potassium permanganate solution is decolourised by acidified iron(II) sulfate solution.(d) sulfur dioxide is bubbled through an acidified solution ...
Copper oxide ores are usually treated by a different process, called leaching, in which the copper in the ore is dissolved in a leaching solution (usually dilute sulfuric acid); pure copper is recovered by electrolysis. Alternatively, the solution is treated with iron to precipitate the so-calle...
with chlorine, chlorine trifluoride, fluorine (above 121℃), and hydrazinium nitrate (above 70'). Reacts violently with C2H2, bromates, chlorates, iodates, (Cl2 + OF2), dimethyl sulfoxide + trichloroacetic acid, ethylene oxide, H202, hydrazine mononitrate, hydrazoic acid, H2S + air, Pb(...
When nitric acid ionizes in water, what ions are formed? Explain how to predict net ionic reactions. What information does a net ionic equation give? An aqueous solution of sodium sulfate is allowed to react with an aqueous solution of lead(II) nitrate. The complete ionic equation conta...
Copper cannot replace hydrogen in an acidic aqueous solution, and is also insoluble in hydrochloric acid and sulfuric acid without dissolved oxygen, but is soluble in nitric acid having an oxidizing action. Copper and alkali solution is very slow, but easy to react with ammonia, the formation ...
