So, the answer is: fHC II (concentration) ten places N82? △? . ? Ground ncii2+c12 =+2h2o;
(2) (1) copper sulfate absorbs water to generate blue copper sulfate crystals, which contain water vapor after inspection.
So, the answer is: anhydrous copper sulfate; Prove that water vapor is produced;
(2) Dry color cloth strips do not fade, indicating that chlorine has no bleachability; Wet colored cloth strips fade, and chlorine reacts with water to produce hydrochloric acid and hypochlorous acid. Hydrochloric acid has no bleachability, so the substance that discolors colored cloth strips is hypochlorous acid, so hypochlorous acid has bleachability.
Therefore, the answer is: chlorine is not bleached, but hypochlorous acid is bleached;
(3) Chlorine gas is absorbed by carbon chloride in F to prevent interference with the inspection of hydrogen chloride in F. Hydrogen chloride enters G device to react with silver nitrate to generate silver chloride and nitric acid, and the reaction ionic equation is G++C Ⅱ-GC Ⅱ.
So, the answer is: it G++C2-it GC 2 ↓;
(It) chlorine reacts with water to generate hydrochloric acid, which interferes with the test of hydrogen chloride in G, so a device is added between F and G to test whether chlorine gas is completely absorbed with potassium iodide starch test solution, or to test the existence of chlorine gas with colored cloth strips;
So the answer is: f and g; Potassium iodide starch test solution or wet colored cloth strip;
(f) When the amount of F-F8 dichloride (measured under standard conditions) is 8. 2 to O-2, the oxidation product C-Ta (C-Dio) 2 can be obtained theoretically. According to the chemical equation of the reaction, C-Ta (OH) 2+C-Dio2 = C-Ta 2+C-Ta (C-Dio) 2+2H2O.
So the answer is:1f. It ...
