Abstract
The utility model discloses a kind of improved Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment device, comprise reactor, eudiometer tube, leveling bottle, constant temperature water bath, silicone tube, described reactor is that bifurcated separates but bitubular reactor that top communicates again in the middle of one, described bitubular reactor is connected with eudiometer tube by silicone tube, T-valve, the other end of described eudiometer tube is connected with leveling bottle by silicone tube again, and described bitubular reactor is positioned at constant temperature water bath.By common response device is modified into bitubular reactor, on the basis that does not affect experiment effect, simplify experimental procedure, not only experimental result accurately and reliably, and avoid student to break glass apparatus because operative skill is not yet done, also reduced repetition and the medicine loss in experimentation, ensured safety when student tests simultaneously.
Description
Technical field
The utility model relates to a kind of chemical experiment device, relates in particular to a kind of Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment device.
Background technology
The course that practicality is very strong is not only in chemical experiment, and is impart knowledge, technical ability, and scientific spirit and quality are cultivated in training science thinking, implements in full the effective form of chemical education.In Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment, H
2o
2solution and KI (catalyzer) solution can not add in people's reactor simultaneously, otherwise reaction has started but volume metering cannot carry out simultaneously.Conventionally the method adopting is, by H
2o
2solution and KI solution are respectively charged in the reactor of a little uncovered plastic bottle and a tool plug, then carefully uncovered plastic bottle are placed in to reactor, treat that whole device installs, then manage to turn over bottle, start timing and measure.When this experimental technique is placed, need certain operation skill, and because bottle is always in reactor, stirring dynamics is little is difficult for liquid in bottle all to mix, the too large reactor wall of stirring dynamics easily damages and causes the failure of an experiment.
Summary of the invention
The purpose of this utility model is exactly for the above problem existing in prior art, provides a kind of easy to operate, measures accurately Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment device simple in structure.
The purpose of this utility model is achieved through the following technical solutions, this Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment device comprises reactor, eudiometer tube, leveling bottle, constant temperature water bath, silicone tube, described reactor is that bifurcated separates but bitubular reactor that top communicates again in the middle of one, described bitubular reactor is connected with eudiometer tube by silicone tube, T-valve, the other end of described eudiometer tube is connected with leveling bottle by silicone tube again, and described bitubular reactor is positioned at constant temperature water bath.
When experiment, use transfer pipet quantitative H
2o
2fill respectively in two cylinders of people's reactor with KI solution, after a whole set of experimental provision installs, the solvent that shake reactor makes to add two cylinders in people's reactor mutually mixes and starts to record experimental data.
Of the present utility model producing effect: by common response device is modified into bitubular reactor, on the basis that does not affect experiment effect, simplify experimental procedure, not only experimental result accurately and reliably, and avoid student to break glass apparatus because operative skill is not yet done, also reduced repetition and the medicine loss in experimentation, ensured safety when student tests simultaneously.

Fig. 1 is schematic diagram of the present utility model
In figure: 1, reactor 2, eudiometer tube 3, leveling bottle 4, silicone tube 5, T-valve 6, constant temperature water bath
Embodiment
As shown in Figure 1, this Catalytic Decomposition of Hydrogen Peroxide reaction rate determination experiment device comprises reactor 1, eudiometer tube 2, leveling bottle 3, constant temperature water bath 6, silicone tube 4, reactor 1 is that bifurcated separates but bitubular reactor that top communicates again in the middle of one, reactor 1 is connected with eudiometer tube 2 by silicone tube 4, T-valve 5, the other end of eudiometer tube 2 is connected with leveling bottle 3 by silicone tube 4 again, and bitubular reactor 1 is positioned at constant temperature water bath 6.
When experiment, use transfer pipet quantitative H
2o
2be respectively charged in two cylinders of reactor 1 with KI solution, after a whole set of experimental provision installs, shake reactor 1 makes to add the solvent of 1 li of two cylinder of reactor mutually to mix and starts to record experimental data.
