The utility model discloses do the lecture experiment on not only being suitable for the teacher classroom, still be suitable for the student and be grouping experiment, can reduce environmental pollution during the experiment, save the medicine. (B, )
Description
one, technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating experiment junior middle school chemistry textbook being probed into particle movement.
two, background technology
the experiment of particle movement probed into by ninth grade chemistry the 63rd page, the textbook that Shanghai education publishing house publishes in January, 2012, is demonstration like this: [experiment 1] adds 20mL distilled water in beaker A, instills 2 ~ 3 phenolphthalein test solutions, obtains solution first in textbook.1 ~ 2 strong aqua is dripped, observe phenomena in solution first.[experiment 2] reconfigures first solution in beaker C.In beaker B, add 3 ~ 5mL strong aqua, with a large beaker, two beakers are covered on together, observation experiment phenomenon.Textbook does experiment existing defects like this: the ammonia 1, evaporated from strong aqua easily reveals contaminated environment in atmosphere.2, drug dosage is comparatively large, waste.3, textbook device is not suitable for student and does grouping experiment.
three, utility model content
the utility model object is to provide a kind of experimental provision that particulate constantly moves that confirms.The experiment using the utility model to probe into particle movement can not only reduce environmental pollution, and drug dosage is few.The utility model is not only applicable to classroom does lecture experiment, but also applicable student does grouping experiment.
the purpose of this utility model realizes by the following method:
confirm to be primarily characterized in that the experimental provision that particulate constantly moves: it by wide-necked bottle (1), rubber stopper with double hole (3), wireway (4), balloon (5), wall digging the test tube (8) of a hole (6), single hole rubber stopper (9), syringe (10) form.
the cotton (2) of appropriate phenolphthalein test solution moistening mistake is housed in wide-necked bottle (1), and wall digs in the test tube (8) of a hole (6) and appropriate calcium oxide (7) is housed, syringe (10) is inner is equipped with strong aqua.
experimentation: the impermeability of first testing fixture, then will use the cotton (2) of the moistening mistake of phenolphthalein test solution to put in wide-necked bottle (1) in right amount.Appropriate calcium oxide (7) is put into, and wall digs in the test tube (8) of a hole (6), and the test tube (8) then wireway (4) He Bishang being dug a hole (6) is inserted on rubber stopper with double hole (3) respectively.With test tube (8) the jam-pack wide-necked bottle (1) digging a hole (6) with wireway (4) He Bishang, the aperture on test tube (8) wall is arranged in wide-necked bottle (1).The wireway (4) of rubber stopper with double hole (3) outer end is fixed a balloon (5), and balloon (5) plays adjustable pressure.Appropriate strong aqua is extracted, then by the needle pierces single hole rubber stopper (9) of syringe (10), with the test tube (8) single hole rubber stopper (9) the jam-pack wall of syringe (10) digging a hole (6) with syringe (10).During experiment, touch syringe (10), to appropriate strong aqua instillation wall dig in the test tube (8) of a hole (6), moisture in strong aqua and calcium oxide react releases a large amount of heat, accelerate the volatilization of strong aqua, the ammonia volatilized is from aperture (6) effusion test tube (5) wall, can see after a period of time in wide-necked bottle (1) and become red with the cotton (2) of the moistening mistake of phenolphthalein test solution, this is because strong aqua has volatility, the ammonia molecule evaporated constantly moves, when contacting with the cotton (2) by the moistening mistake of phenolphthalein test solution in ammonia molecular motion to wide-necked bottle (1), cotton becomes red, this phenomenon sufficient proof particulate is constantly motion.
the beneficial effects of the utility model are: the experiment 1, probing into particle movement with the utility model demonstration, because reaction is what to occur in airtight container, the ammonia volatilized from strong aqua is not easily diffused in air, so decrease environmental pollution.2, drug dosage is few.3, the utility model highly versatile, can reuse, and has both been suitable on classroom and has done lecture experiment, is suitable for again 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) wide-necked bottle (2) is equipped with the syringe of strong aqua with test tube (9) the single hole rubber stopper (10) cotton (3) rubber stopper with double hole (4) wireway (5) balloon (6) aperture (7) calcium oxide (8) wall of the moistening mistake of phenolphthalein test solution digging a hole
five, embodiment
below in conjunction with embodiment, the utility model is described in further detail:
confirm to be primarily characterized in that the experimental provision that particulate constantly moves: it by wide-necked bottle (1), rubber stopper with double hole (3), wireway (4), balloon (5), wall digging the test tube (8) of a hole (6), single hole rubber stopper (9), syringe (10) form.
the cotton (2) of appropriate phenolphthalein test solution moistening mistake is housed in wide-necked bottle (1), and wall digs in the test tube (8) of a hole (6) and appropriate calcium oxide (7) is housed, syringe (10) is inner is equipped with strong aqua.
using method of the present utility model: the impermeability of first testing fixture, then will use the cotton (2) of the moistening mistake of phenolphthalein test solution to put in wide-necked bottle (1) in right amount.Appropriate calcium oxide (7) is put into, and wall digs in the test tube (8) of a hole (6), and the test tube (8) then wireway (4) He Bishang being dug a hole (6) is inserted on rubber stopper with double hole (3) respectively.With test tube (8) the jam-pack wide-necked bottle (1) digging a hole (6) with wireway (4) He Bishang, the aperture on test tube (8) wall is arranged in wide-necked bottle (1).The wireway (4) of rubber stopper with double hole (3) outer end is fixed a balloon (5), and balloon (5) plays adjustable pressure.Appropriate strong aqua is extracted, then by the needle pierces single hole rubber stopper (9) of syringe (10), with the test tube (8) single hole rubber stopper (9) the jam-pack wall of syringe (10) digging a hole (6) with syringe (10).During experiment, touch syringe (10), to appropriate strong aqua instillation wall dig in the test tube (8) of a hole (6), moisture in strong aqua and calcium oxide react releases a large amount of heat, accelerate the volatilization of strong aqua, the ammonia volatilized is from aperture (6) effusion test tube (5) wall, can see after a period of time in wide-necked bottle (1) and become red with the cotton (2) of the moistening mistake of phenolphthalein test solution, this is because strong aqua has volatility, the ammonia molecule evaporated constantly moves, when contacting with the cotton (2) by the moistening mistake of phenolphthalein test solution in ammonia molecular motion to wide-necked bottle (1), cotton becomes red, this phenomenon sufficient proof particulate is constantly motion.The utility model has the advantages that: 1, test and carry out in airtight container, the ammonia volatilized from strong aqua is not easily diffused in air, so decrease environmental pollution.2, drug dosage is few.3, highly versatile, can reuse, and has both been suitable on classroom and has done lecture experiment, is suitable for again student and does grouping experiment.
