Description
one, technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating the experiment of senior chemistry textbook By Electrolysis copper chloride solution.
two, background technology
the experiment of senior chemistry textbook " chemical principle " (taking as an elective course) the 18th page of electrolytic chlorination copper solution that Jiangsu education publishing house publishes in June, 2007: fill copper chloride solution in U-shaped pipe, insert two graphite rods as electrode, connect direct supply, moistening starch potassium iodide paper is placed near anode, the phenomenon in observation U-shaped pipe and the change of test paper color.Experiment existing defects is done: the chlorine produced after copper chloride solution electrolysis easily reveals contaminated environment in atmosphere with the experimental provision in textbook; Experimental provision in 2 textbooks is not suitable for student and does grouping experiment.
three, utility model content
the utility model object is the experimental provision providing a kind of electrolytic chlorination copper solution and check its product characteristics.Make device not be only applicable to classroom does lecture experiment, be also applicable to student and do grouping experiment, and can environmental pollution be reduced.
the purpose of this utility model realizes by the following method:
a kind of electrolytic chlorination copper solution and check the experimental provision of its product characteristics, be primarily characterized in that: it is by the iron stand (1) with iron clamp (2), the U-shaped pipe (3) of two end band arms of copper chloride solution is housed, first graphite rod (4), first rubber stopper (5), first wire (6), direct supply (7), second wire (8), second rubber stopper (9), second graphite rod (10), first emulsion tube (11), first drying tube (13) of moistening red paper slip (12) is housed, 3rd rubber stopper (14), second drying tube (16) of moistening starch potassium iodide paper (15) is housed, 4th rubber stopper (17), first wireway (18), second emulsion tube (19), second wireway (20), beaker (21) composition of sodium hydroxide solution is housed.
experimentation: first connect instrument, the impermeability of testing fixture.Saturated copper chloride solution is put in the U-shaped pipe (3) of two end band arms, and the liquid level at two ends is a little less than the height of arm.Be fixed on iron stand (1) with the U-shaped pipe (3) of iron clamp (2) by two end band arms.With U-shaped pipe (3) the left end mouth of pipe of the first rubber stopper (5) the jam-pack two end band arm of band first graphite rod (4); With U-shaped pipe (3) the right-hand member mouth of pipe of the second rubber stopper (9) the jam-pack two end band arm of band second graphite rod (10).The two ends of the first wire (6) are connected with the negative pole of direct supply (7) with first graphite rod (4) of the first rubber stopper (5) outer end respectively; The two ends of the second wire (8) are connected with the positive pole of direct supply (7) with second graphite rod (10) of the second rubber stopper (9) outer end respectively.That less with the first drying tube (13) that moistening red paper slip (12) is housed for the right-hand member arm of the U-shaped pipe (3) of two end band arms end is connected by emulsion tube (11); That end mouth of pipe that 3rd rubber stopper (14) jam-pack first drying tube (13) is larger, the second drying tube (16) is inner is equipped with moistening starch potassium iodide paper (15), and that end that the second drying tube (16) is less is connected with the 3rd rubber stopper (14).With that end mouth of pipe that the 4th rubber stopper (17) jam-pack second drying tube (16) of the first wireway (18) is larger.First wireway (18) and the second wireway (20) couple together by the second emulsion tube (19), and the end of the second wireway (20) puts in the beaker (21) that sodium hydroxide solution is housed.Then, open direct supply (7) switch, switch on power, can see that the second graphite rod (10) be connected with direct supply (7) positive pole is upper and produce a large amount of bubble, collect at U-shaped pipe (3) right-hand member of two end band arms and have yellowish green gas, this is the chlorine that copper chloride solution produces when logical direct current; The first graphite rod (4) be connected with direct supply (7) negative pole produces red material gradually, and this is the copper that copper chloride solution produces when logical direct current.Moistening red paper slip (12) in first drying tube (13) fades gradually, this is because chlorine contacts with moistening red paper slip, chlorine and water react and creates hydrochloric acid and hypochlorous acid, and hypochlorous acid makes the redness of paper slip take off; Moistening starch potassium iodide paper in second drying tube (16) becomes blue, this is because chlorine contact with moistening starch potassium iodide paper (15) and chemical reaction occurs generates iodine, iodine and starch storage crop show blueness.Unnecessary chlorine is absorbed by sodium hydroxide solution, can not contaminated air, therefore very environmental protection.
the beneficial effects of the utility model are: the chlorine that 1, copper chloride solution produces after leading to direct current not easily reveals safety, environmental protection, pollution-free in atmosphere.2, the phenomenon that the moistening red paper slip of chlorine fades, makes moistening starch potassium iodide paper become blue can be observed simultaneously.3, be not only applicable to classroom does lecture experiment, be also applicable to student and do grouping experiment.
four, accompanying drawing explanation
