one, technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating the experiment of product in laboratory carbon dioxide on junior middle school chemistry textbook.
two, background technology
the laboratory preparation of ninth grade chemistry textbook the 44th page of carbon dioxide that Shanghai in January, 2012 education publishing house publishes, operate like this in textbook: in conical flask, fill appropriate lime stone, then the rubber stopper with double hole of long neck funnel and wireway is with beyond the Great Wall, in long neck funnel, add appropriate watery hydrochloric acid, use upwards air-discharging method to collect carbon dioxide.Following defect is there is: drug dosage is large with the experimental provision preparing CO 2 gas in textbook; Reaction can not be controlled occur at any time and stop at any time.Improve the experimental provision in textbook, make the device after improvement no longer include above defect.
three, utility model content
the utility model object is the experimental provision providing a kind of product in laboratory carbon dioxide, uses the utility model preparing CO 2 gas, can control reaction and occurs at any time and stop at any time, easy to use; Medicine can also be saved.
the purpose of this utility model realizes by the following method:
an experimental provision for product in laboratory carbon dioxide, is primarily characterized in that: it by being equipped with the beaker (1) of watery hydrochloric acid, the drying tube (4) that copper mesh (2) and lime stone (3) are housed, rubber stopper (5), the first wireway (6), emulsion tube (7), spring clamp (8), the second wireway (9), glass sheet (10), gas bottle (11) form.
rubber stopper (5) jam-pack with the first wireway (6) is equipped with that larger end mouth of pipe of the drying tube (4) of copper mesh (2) and lime stone (3).The emulsion tube (7) of band spring clamp (8) connects the first wireway (6) and second wireway (9) of rubber stopper (5) outer end, and the end of the second wireway (9) is inserted into the bottom of gas bottle (11), and glass sheet (10) is placed on gas bottle (11) mouth.The drying tube (4) that copper mesh (2) and lime stone (3) are housed is placed in the beaker (1) that watery hydrochloric acid is housed, and less that end of drying tube (4) mouth of pipe down.
experimentation: connect instrument, the impermeability of testing fixture.First copper mesh (2) is put in drying tube (4), and then it is inner that appropriate lime stone (3) is put into drying tube (4), and be placed on copper mesh (2).First wireway (6) is inserted on rubber stopper (5), rubber stopper (5) jam-pack with the first wireway (6) is equipped with that larger end mouth of pipe of the drying tube (4) of copper mesh (2) and lime stone (3).The first wireway (6) and second wireway (9) of rubber stopper (5) outer end is connected with the emulsion tube (7) of band spring clamp (8), the end of the second wireway (9) is inserted into the bottom of gas bottle (11), glass sheet (10) is placed on gas bottle (11) mouth.The drying tube (4) that copper mesh (2) and lime stone (3) are housed is placed in the beaker (1) that watery hydrochloric acid is housed, less that end of drying tube (4) mouth of pipe down.During experiment, open spring clamp (8), watery hydrochloric acid in beaker (1) enters drying tube (4) from the lower end of drying tube (4) and contacts with lime stone (3), at this moment can see that lime stone (3) surface produces a large amount of bubble, after a period of time, the match that ignite is placed on gas bottle (11) mouth, if the match that ignite extinguishes, proves that carbon dioxide is collected full.After experiment, fastening spring folder (8), in drying tube (4), gas pressure intensity increases, and liquid level declines, and lime stone (3) and watery hydrochloric acid disengage, and reaction stopping is carried out.
the beneficial effects of the utility model are: can control reaction and occur at any time and stop at any time, easy to use; Medicine can also be saved.Highly versatile, can reuse, and is not only suitable for teacher and does lecture experiment, is also suitable for student and does grouping experiment.
four, accompanying drawing explanation
fig. 1 is structural drawing of the present utility model.
mark in figure represents respectively:
(1) beaker (2) copper mesh (3) lime stone (4) drying tube (5) rubber stopper (6) first wireway (7) emulsion tube (8) spring clamp (9) second wireway (10) glass sheet (11) gas bottle of watery hydrochloric acid is housed
five, embodiment
below in conjunction with embodiment, the utility model is described in further detail:
an experimental provision for product in laboratory carbon dioxide, is primarily characterized in that: it by being equipped with the beaker (1) of watery hydrochloric acid, the drying tube (4) that copper mesh (2) and lime stone (3) are housed, rubber stopper (5), the first wireway (6), emulsion tube (7), spring clamp (8), the second wireway (9), glass sheet (10), gas bottle (11) form.
