Description
one, technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating the experiment that on senior chemistry textbook, the concentrated sulphuric acid and charcoal react.
two, background technology
the senior chemistry 1(that Shandong science tech publishing house in July, 2014 publishes is required) experiment of reacting of textbook the 89th page of concentrated sulphuric acid and charcoal, usually in test tube, complete this experiment, but the concentrated sulphuric acid and charcoal react the sulphuric dioxide meeting contaminated air produced, three kinds of products are difficult to check respectively, therefore existing defects.Improve the experimental provision in textbook, do experiment with the device after improving and can overcome above defect, not only environmental protection, and the three kinds of products concentrated sulphuric acid and charcoal being checked respectively to react generate.
three, utility model content
the utility model object is to provide a kind of concentrated sulphuric acid and charcoal react and check the experimental provision of its product.The experiment using the utility model to do the concentrated sulphuric acid and charcoal to react, phenomenon is obviously, environmental protection, safe, pollution-free, can check out three kinds of products respectively.The utility model is not only applicable to classroom does lecture experiment, is also applicable to student and does grouping experiment, and can reduce environmental pollution.
the purpose of this utility model realizes by the following method:
a kind of concentrated sulphuric acid and charcoal react and check the experimental provision of its product, it is characterized in that: it is by the iron stand (1) with iron clamp (23), spirit lamp (2), the tool that charcoal (22) is housed props up test tube (3), first single hole rubber stopper (4), the separating funnel (5) of the concentrated sulphuric acid is housed, first emulsion tube (6), the drying tube (7) of white copper sulphate solid (8) is housed, second single hole rubber stopper (9), one 90 ° of wireway (10), first wide-necked bottle (11) of fuchsin solution is housed, first rubber stopper with double hole (12), 2 90 ° of wireway (13), second emulsion tube (14), 3 90 ° of wireway (15), second rubber stopper with double hole (16), second wide-necked bottle (17) of acid permanganate soln is housed, 4 90 ° of wireway (18), 3rd emulsion tube (19), 5 90 ° of wireway (20), beaker (21) composition of clarification lime water is housed.
experimentation: connect instrument, the impermeability of testing fixture.Then appropriate charcoal (22) being put into tool props up in test tube (3), with iron clamp (23), the tool that charcoal (22) is housed being propped up test tube (3) is fixed on iron stand (1), and the first single hole rubber stopper (4) jam-pack tool of band separating funnel (5) props up the mouth of pipe of test tube (3).Arm tool being propped up test tube (3) with the first emulsion tube (6) and that end drying tube (7) of white copper sulphate solid (8) being housed less couple together.The first rubber stopper with double hole (12) jam-pack with the one 90 ° of wireway (10) and the 2 90 ° of wireway (13) is equipped with first wide-necked bottle (11) of fuchsin solution, stretches into the one 90 ° of wireway (10) of being equipped with in first wide-necked bottle (11) of fuchsin solution and inserts in fuchsin solution.The other end of the one 90 ° of wireway (10) is connected with the second single hole rubber stopper (9), is with that end mouth of pipe that the second single hole rubber stopper (9) jam-pack drying tube (7) of the one 90 ° of wireway (10) is larger; The second rubber stopper with double hole (16) jam-pack with the 3 90 ° of wireway (15) and the 4 90 ° of wireway (18) is equipped with second wide-necked bottle (17) of acid permanganate soln, stretch into the 3 90 ° of wireway (15) of being equipped with in second wide-necked bottle (17) of acid permanganate soln to insert in acid permanganate soln, the 2 90 ° of wireway (13) and the 3 90 ° of wireway (15) couple together by the second emulsion tube (14).4 90 ° of wireway (18) and the 5 90 ° of wireway (20) couple together by the 3rd emulsion tube (19), the other end of the 5 90 ° of wireway (20) inserts in the beaker (21) that clarification lime water is housed, spirit lamp (2) is placed on tool and props up immediately below test tube (3), regulates tool and props up distance between test tube (3) and spirit lamp (2).During experiment, in separating funnel (5), add the concentrated sulphuric acid, open the switch of separating funnel (5), allow the concentrated sulphuric acid flow to tool and prop up in test tube (3) and contact with charcoal (22).Light spirit lamp (2), test tube (3) bottom-heated is propped up at tool with spirit lamp flame envelope, at this moment can see that the concentrated sulphuric acid and charcoal (22) react and produce a large amount of bubble, after a period of time, white copper sulphate solid (8) in drying tube (7) becomes blue colored crystal, and this proves that the concentrated sulphuric acid and charcoal (22) react and generates water; Can also see that the fuchsin solution in the first wide-necked bottle (11) fades, this proves that the concentrated sulphuric acid and charcoal react and generates sulfur dioxide gas.When the gas generated is by the second wide-necked bottle (17) that acid permanganate soln is housed, sulfur dioxide gas is removed, remaining gas enters in the beaker (21) that clarification lime water is housed, and the lime water of clarification becomes muddy, and this proof has carbon dioxide to generate.
the beneficial effects of the utility model are: the sulfur dioxide gas that 1, reaction generates can not be revealed in atmosphere, very environmental protection.2, the three kinds of products concentrated sulphuric acid and charcoal being checked out respectively to react generate.3, be not only applicable to classroom does lecture experiment, be also applicable to student and do grouping experiment.
