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 junior middle school chemistry textbook, charcoal burns in oxygen.
two, background technology
the experiment that in the nine-year compulsory education chemical textbook first volume the 31st page published Shanghai education publishing house in January, 2012 [movable with probe into], charcoal burns in oxygen demonstrates like this: clamp charcoal with crucible tongs, after lighting in atmosphere, again the charcoal lighted is put into combustion spoon, from top to bottom slowly stretch in the gas bottle of the full oxygen of collection.Do experiment existing defects like this in teaching material: the oxygen that 1, will prepare a gas bottle bottle in advance, trouble, wastes many time.2, charcoal burning product fails to check.
three, utility model content
the utility model object is the experimental provision providing a kind of charcoal and oxygen reaction.Use the utility model to test, the defect of experimental provision in teaching material can be overcome, easy and simple to handle, and the product of charcoal burning can be checked out, phenomenon is obvious.The utility model versatility is wide, is not only suitable on classroom and does lecture experiment, is also suitable for student and does grouping experiment.
the purpose of this utility model realizes by the following method:
an experimental provision for charcoal and oxygen reaction, is primarily characterized in that: it by being equipped with the wide-necked bottle (1) of characteristic of modest manganese powder (13), the first rubber stopper (2), the separating funnel (3) that superoxol is housed, the first wireway (4), the second rubber stopper (5), glass three-way pipe (6), the iron stand (7) of band iron clamp, the 3rd rubber stopper (8), the second wireway (9), the transparent combustion spoon (10) that charcoal (14) is housed, the large beaker (11) that clarification lime water is housed, the 4th rubber stopper (12) form.
first rubber stopper (2) jam-pack of band separating funnel (3) and wireway (4) is equipped with the wide-necked bottle (1) of characteristic of modest manganese powder (13), glass three-way pipe (6) is horizontally fixed on iron stand (7), a mouth of pipe of glass three-way pipe (6) upwards, and be positioned at the right side of iron stand (7), two other mouth of pipe of glass three-way pipe (6) lays respectively at the right and left of iron stand (7), with the left end mouth of pipe of the second rubber stopper (5) jam-pack glass three-way pipe (6) of the first wireway (4); With the right-hand member mouth of pipe of the 3rd rubber stopper (8) jam-pack glass three-way pipe (6) of the second wireway (9); With the 4th rubber stopper (12) jam-pack glass three-way pipe (6) mouth of pipe upwards of transparent combustion spoon (10), the 3rd wireway (9) stretches in the large beaker (11) that clarification lime water is housed.
experimentation: the impermeability of first testing fixture, getting characteristic of modest manganese powder (13) puts in wide-necked bottle (1), with the first rubber stopper (2) the jam-pack wide-necked bottle (1) being with separating funnel (3) and wireway (4), with iron clamp, glass three-way pipe (6) is horizontally fixed on iron stand (7), upwards, two other mouth of pipe of glass three-way pipe (6) lays respectively at the right and left of iron stand (7) to a mouth of pipe of glass three-way pipe (6).With the left end mouth of pipe of the second rubber stopper (5) jam-pack glass three-way pipe (6) with the first wireway (4); With the right-hand member mouth of pipe of the 3rd rubber stopper (8) jam-pack glass three-way pipe (6) of the second wireway (9), the 3rd wireway (9) is stretched in the large beaker (11) that clarification lime water is housed.Proper amount of hydrogen peroxide solution is added in separating funnel (3).Then clamp a fritter charcoal with crucible tongs, be heated to rubescent in atmosphere, observe the phenomenon that charcoal burns in atmosphere.Open the switch of separating funnel (3), in separating funnel (3), appropriate superoxol flows to the inner rear switch of closing separating funnel of wide-necked bottle (1), a large amount of bubbles is produced after superoxol contacts with manganese dioxide powder, this is the oxygen that peroxide decomposition produces, and the oxygen of generation is entered in glass three-way pipe (6) by the first wireway (4).Rubescent charcoal is placed in transparent combustion spoon (10), will, with the 4th rubber stopper (12) jam-pack glass three-way pipe (6) mouth of pipe upwards of transparent combustion spoon (10), the red heat charcoal in transparent combustion spoon (10) be made to be positioned at the centre in glass three-way pipe (6) space.At this moment can see that charcoal burning is more prosperous, sends white light, and constantly reduce, can see that the gas of generation is entered in large beaker (11) by the second wireway (9) simultaneously and contact with clarification lime water, clarification lime water becomes muddy.This demonstrate that charcoal is more prosperous in ratio of combustion air in oxygen, produce the carbon dioxide that clarification lime water can be made to become muddy.
the beneficial effects of the utility model are: 1, control the amount of superoxol by separating funnel, reach lasting oxygenous effect, make the charcoal burning Geng Wang in glass three-way pipe (6), more lasting.2, the carbon dioxide that the oxygen stream that peroxide decomposition produces makes charcoal burning generate enters smoothly in large beaker (11) and contacts with clarification lime water, and phenomenon is obvious.3, the utility model highly versatile, had both been suitable for teacher and had done lecture experiment, and be suitable for again student and do grouping experiment.
