Description
Technical field
The utility model relates to a kind of microscale laboratory device of sodium peroxide character, belongs to chemistry teaching field of tool.
Background technology
At present, the property experiment of sodium peroxide is one of emphasis of middle school chemistry experiment teaching, at contest or classroom teaching, many teachers complain numerous and diverse, the deficiency of time of experiment, as a result, demonstration in a great rush, causes teaching not complete smoothly, not only have impact on the successes achieved in teaching of teacher, also have impact on the understanding of students to the chemical property of sodium peroxide; And when the chemical property experiment doing sodium peroxide, generally all use asbestos gauge, but asbestos Netease is corroded and burns out, so often do time experiment and all change once, inconvenience very.
Summary of the invention
(1) technical matters that will solve
For solving the problem, the utility model proposes a kind of simple and reasonable, easy to use, can complete at short notice sodium peroxide reaction there is chemical property, win the time for teacher attends class, and be conducive to student carries out the sodium peroxide character of experiment outward microscale laboratory device within the class period.
(2) technical scheme
The microscale laboratory device of sodium peroxide character of the present utility model, comprises reaction bulb, and is arranged on the evaporating dish of reaction bulb inside, and is arranged on the expanded rubber plug of reaction bulb bottle mouth position; Described reaction bulb side is provided with the first syringe; By the first tubes connection between described reaction bulb and the first syringe; Described first conduit is provided with valve; Described reaction bulb upper end is provided with the second syringe; Described reaction bulb side is provided with penicillin bottle; By the second tubes connection between described penicillin bottle and reaction bulb.
Further, sodium peroxide is provided with in described evaporating dish.
Further, carbon dioxide is provided with in described first syringe.
Further, described first conduit is provided with red paper slip, and red paper slip is inner at reaction bulb.
Further, distilled water is provided with in described second syringe.
Further, sodium hydroxide solution is provided with in described penicillin bottle.
(3) beneficial effect
The utility model compared with prior art, it has following beneficial effect: the microscale laboratory device of sodium peroxide character of the present utility model, by the setting of evaporating dish, can solve the situation of testing at every turn and terminating rear asbestos gauge and being all corroded or burning out and can not reuse, evaporating dish cleaning is simultaneously more convenient; It is simple and reasonable, easy to use, and chemical property occurs in the institute that can complete sodium peroxide reaction at short notice, has won the time for teacher attends class, and is conducive to student and outward carries out experiment within the class period.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-reaction bulb; 2-evaporating dish; 3-expanded rubber plug; 4-first syringe; 5-first conduit; 6-valve; 7-second syringe; 8-penicillin bottle; 9-second conduit.
Embodiment
The microscale laboratory device of a kind of sodium peroxide character as shown in Figure 1, comprises reaction bulb 1, and is arranged on the evaporating dish 2 of reaction bulb 1 inside, and is arranged on the expanded rubber plug 3 of reaction bulb 1 bottle mouth position; Described reaction bulb 1 side is provided with the first syringe 4; Be connected by the first conduit 5 between described reaction bulb 1 with the first syringe 4; Described first conduit 5 is provided with valve 6; Described reaction bulb 1 upper end is provided with the second syringe 7; Described reaction bulb 1 side is provided with penicillin bottle 8; Described penicillin bottle 8 is connected by the second conduit 9 with between reaction bulb 1.
Wherein, sodium peroxide is provided with in described evaporating dish 2; Carbon dioxide is provided with in described first syringe 4; Described first conduit is provided with red paper slip, and red paper slip is inner at reaction bulb 1; Distilled water is provided with in described second syringe 7; Sodium hydroxide solution is provided with in described penicillin bottle 8.
In above structure, open valve, in the first syringe, carbon dioxide pushes reaction bulb and reacts with sodium peroxide, surface sodium peroxide bleaches gradually, move on in penicillin bottle bottleneck by the batten of band Mars, batten resume combustion, red paper slip moistening on the first conduit in reaction bulb fades; Valve-off, a moment later, move on in penicillin bottle bottleneck by the batten of band Mars, batten not resume combustion, now, the second syringe pushes distilled water to reaction bulb, observes peroxidating sodium and water reaction, moves on in penicillin bottle bottleneck, batten resume combustion by the batten of band Mars.
The microscale laboratory device of sodium peroxide character of the present utility model, by the setting of evaporating dish, can solve the situation of testing at every turn and terminating rear asbestos gauge and being all corroded or burning out and can not reuse, evaporating dish cleaning is simultaneously more convenient; It is simple and reasonable, easy to use, and chemical property occurs in the institute that can complete sodium peroxide reaction at short notice, has won the time for teacher attends class, and is conducive to student and outward carries out experiment within the class period.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
