Description
Technical field
This utility model relates to experimental provision, is specifically related to a kind of modified model oxygen and produces the experimental provision with character.
Background technology
" producing and character of oxygen " experiment is emphasis and the difficult point of junior three chemistry.Oxygen character lecture experiment at least needs 5 bottles of oxygen, if ining succession 3 class's teaching, at least wants 15 bottles.Finding in field research process, if keeping oxygen in advance well, being positioned ready for room, oxygen is easy to loss and falls, and by the gas collecting bottle of full for collection oxygen, in classroom during transport, also easily causes oxygen loss, and oxygen concentration declines, lecture experiment failure.
Summary of the invention
The purpose of this utility model is in that: provides a kind of modified model oxygen to produce the experimental provision with character, saves the Preparatory work of experiment time, improves demonstrating effect, facilitate the demonstration of experiment teaching of teacher.
Technical solution of the present utility model is: this experimental provision includes conical flask, separatory funnel and gas collecting bottle, separatory funnel inserts in conical flask by bottle stopper, conical flask and gas collecting bottle are interconnected by airway, it is characterized in that: the bottom of conical flask sets waste liquid outlet, the bottom of gas collecting bottle sets gas port, airway one end connection conical flask, the gas port of airway other end connected set gas cylinder.
When oxygen is produced, conical flask adds manganese dioxide cement ball, separatory funnel adds the hydrogen peroxide of 10%, the hydrogen peroxide by 10% from separatory funnel steadily, put down equably, in gas collecting bottle, collect oxygen by upwards air-discharging method simultaneously, and test with the batten with Mars full；During oxygen property experiment, stretch into wax candle respectively in gas collecting bottle, Linesless charcoal, iron wire, sulfur carry out burning demonstration.
The utility model has the advantages that: 1, the cement ball of manganese dioxide is more easily recycled than Powdered manganese dioxide, has saved manganese dioxide, good economy performance；2, every experimental phenomena is substantially and last longer, it is easier to excite the interest of Students ' Learning chemistry, more interesting；3, the sulfur dioxide gas produced, more environmental protection are processed in time；4, utilize a gas collecting bottle after improving just can complete 5 property experiments, there is simplicity；5, this device integrate system, take, character, have higher comprehensive；6, this device obtains oxygen in a large number quickly, smoothly, gas collecting bottle sets a little gas port, facilitate and continuously collect and demonstration use, solve teacher's oxygen reserves relevant issues in many classes upper class hour continuously, disposable complete all of oxygen experiment, save the time of chemistry teacher's preparing experiment, ensure that experiment effect, significantly excite interest and student's chemistry learning interest of teacher's experimental teaching, it is also applied for producing and property experiment of the multiple gases such as chlorine, carbon dioxide, practical.

In figure: 1 conical flask, 2 separatory funnels, 3 gas collecting bottles, 4 bottle stoppers, 5 airways, 6 waste liquid outlets, 7 gas ports, 8 Balance Air pressure pipes, 9 drying tubes, 10 rubber tubes, 11 exhaustors, 12 receiving flasks.
Detailed description of the invention
As shown in Figure 1, this experimental provision includes conical flask 1, separatory funnel 2 and gas collecting bottle 3, separatory funnel 2 inserts in conical flask 1 by bottle stopper 4, conical flask 1 and gas collecting bottle 3 are interconnected by airway 5, it is characterized in that: the bottom of conical flask 1 sets waste liquid outlet 6, the bottom of gas collecting bottle 3 sets gas port 7, airway 5 one end connection conical flask 1, the gas port 7 of airway 5 other end connected set gas cylinder 3.
As shown in Figure 2, this experimental provision includes conical flask 1, separatory funnel 2 and gas collecting bottle 3, the bottom of conical flask 1 sets waste liquid outlet 6, the bottom of gas collecting bottle 3 sets gas port 7, separatory funnel 2 inserts in conical flask 1 by bottle stopper 4, and the Balance Air pressure pipe 8 at separatory funnel 2 top is inserted in conical flask 1 also by bottle stopper 4, airway 5 one end connection conical flask 1, airway 5 other end connection drying tube 9, the drying tube 9 gas port 7 by rubber tube 10 connected set gas cylinder 3.
As it is shown on figure 3, gas collecting bottle 3 connects receiving flask 12 by exhaustor 11.
Experimental implementation is as follows:
1, check the air-tightness of device, conical flask adds manganese dioxide cement ball, separatory funnel adds the hydrogen peroxide of 10%；
2, by the hydrogen peroxide of 10% from separatory funnel steadily, put down equably, in gas collecting bottle, collects oxygen by upwards air-discharging method simultaneously, testing with the batten with Mars expires；
3, stretch into wax candle respectively in gas collecting bottle, Linesless charcoal, iron wire, sulfur carry out burning demonstration；
4, need when demonstrating wax candle to connect drying tube, collect dry oxygen, the product after observation experiment；
5, during the burning of demonstration iron wire, a small amount of water is added in the bottom of gas collecting bottle, it is prevented that scorch bottom gas collecting bottle.
