Measure in the experiment of oxidized metal general, experimenter first records the quality m of the front measured object of reaction
0, then by measured object and excessive sour m
1mixing, unoxidized metal and sour complete reaction release a certain amount of gas, and reacted solution need through weighing with scale again, and measuring quality is m
2, according to m
0+ m
1-m
2try to achieve the volume of the gas of generation, and list equation, utilize survey data and calculate.Experimentation is loaded down with trivial details, tediously long, and namely the excessive acid added by experiment waste experimental raw, can cause a certain amount of pollution again to environment, adds experimental period and experimental work amount simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of oxidized metal measuring appliance, according to the volume releasing gas after metal in conical flask and acid reaction, can calculate the quality of trying to achieve oxidized metal.
The utility model in order to the adopted technical scheme that solves the problem is: a kind of oxidized metal measuring appliance, comprises conical flask itself, it is characterized in that: also comprise cock, syringe and gas volume reading pipe; The bottleneck of conical flask is processed with screw thread, mates with the screw thread in cock, and handle is processed in described cock, and conical flask both sides arrange circular hole and threaded hole respectively, is connected respectively with syringe and gas volume reading pipe; Described syringe head outer diameter equals the internal diameter of circular hole, can just imbed, and syringe stack shell is with scale; Also with scale on described gas volume reading tube pipe shaft, the bottom mouth of pipe arranges screw thread, mate with the screw thread of conical flask upper screwed hole, be furnished with a piston in pipe, piston base is minimum cylindrical of thickness, has a stretching bar in the middle of piston, stretching pole length is greater than gas volume reading tube length, there is one handle in stretching masthead portion, and the external diameter of piston equals the internal diameter of gas volume reading tube, can just imbed.
The beneficial effect of utility model is: the utility model saves the weighing of surplus solution after the quality of acid in experimentation in the past and reaction, the volume of the gas directly utilizing reaction to release, calculate the quality of not oxidized metal, thus try to achieve quality and the massfraction of oxidized metal; The acid added during traditional experiment is all excessive, until no longer produce bubble in solution, the utility model utilizes syringe to inject acid solution, when bubble obviously reduces, slowly reduce the injection rate IR of acid until no longer produce bubble, the relative traditional experiment process of this process, environmental protection more, cuts the waste, and decreases experiment fund; Whole chemical reaction environment is closed, and effectively avoid or reduces the interference of external substance to reaction, makes experiment more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, conical flask, 2, cock, 3, syringe, 4, gas volume reading tube, 5, screw thread; 6, handle, 7, circular hole, 8, threaded hole, 9, scale, 10, piston, 11, stretching bar, 12, handle.
Embodiment
Be described further the utility model below in conjunction with accompanying drawing, the utility model is not limited to this,
A kind of oxidized metal measuring appliance, as shown in Figure 1, comprises conical flask 1, cock 2, syringe 3 and gas volume reading pipe 4; The bottleneck of conical flask 1 is processed with screw thread 5, mates with the screw thread in cock 2, and handle 6 is processed in described cock 2, and conical flask 1 both sides arrange circular hole 7 and threaded hole 8 respectively, is connected respectively with syringe 3 and gas volume reading pipe 4; Described syringe 3 head outer diameter equals the internal diameter of circular hole 7, can just inlay into, syringe 3 stack shell is with scale 9, also with scale on gas volume reading tube 4 pipe shaft, the bottom mouth of pipe arranges screw thread, mate with the screw thread on conical flask 1 threaded hole 8, a plastic piston 10 is furnished with in pipe, be minimum cylindrical of thickness bottom piston 10, have a stretching bar 11 in the middle of piston 10, stretching bar 11 length is greater than gas volume reading tube 4 length, and one handle 12 is arranged at stretching bar 11 top, the external diameter of piston 10 equals the internal diameter of gas volume reading tube 4, can just imbed.
Conical flask 1 is reaction vessel, and for preparing gas, outward appearance is flat coniform, and lower wealthy narrow, its pyramidal structure is relatively stable, can not topple over;
Cock 2 material such as glass, the plastics etc. of hard are made, and with the screw thread identical with conical flask 1 bottleneck, conical flask 1 can be made to seal, and cock 2 upper end, with a handles 6, is convenient to hold cock 2 and can outward winding and screw cock 2.
Syringe 3 head outer diameter equals the internal diameter of circular hole 7 on conical flask 1, can just inlay into; Syringe 3 stack shell, with scale 9, is convenient to read the volume of acid of injection and record.
Gas volume reading tube 4 is also with scale, the gas volume that can read, piston 10 is furnished with in pipe, be minimum cylindrical of thickness bottom this piston 10, a stretching bar 11 is had in the middle of piston, stretching bar 11 length is slightly larger than the length of gas volume reading tube 4, one handle 12 is arranged at stretching bar 11 top, be convenient to hold and promote piston 10, the external diameter of piston 10 equals the internal diameter of gas volume reading tube 4 tube wall, can just inlay into, release gas after gas when substance reaction in conical flask 1 and outwards can promote piston 10, until piston 10 inner and outer air pressure is identical.
The utility model specific operation process is as described below: the cock 2 of conical flask 1 bottleneck of outwarding winding, put into the metal to be measured of known quality, screw cock 2, make conical flask 1 bottle sealing, gas volume reading tube 4 is screwed in the threaded hole 8 of the conical flask 1 corresponding with screw thread on it, holds gas volume reading tube 4 and promote piston 10 to the suitable position of scale 9 and record by handle 12; Take out syringe 3, and suck appropriate acid by syringe 3, then syringe 3 is embedded conical flask 1, promote syringe 3, in container, appropriate acid is injected with syringe 3, make acid and metal complete reaction, acid and metal reaction produce gas, and airtight reaction compartment pressure is increased, thus the piston 10 promoted in gas volume reading tube 4, when pressure in question response container is equal with external atmosphere pressure, piston 10 no longer moves, now scale 9 position of recording and analyses 10 again; According to the position of piston 10 before and after the quality of known metal to be measured, reaction and learn chemical equation, can obtain by the quality of the metal of acid oxidase by row equation, thus try to achieve the oxidized quality of former metal to be measured.
The utility model makes the injection of experiment acid more accurately, conveniently and fast, and effectively prevent the undue waste of acid, avoid the link of the rear total solution quality of the quality of the front acid solution of measurement reaction and reaction simultaneously, reduce manual operation reason in this process and cause affecting the shortcoming of experimental result and a kind of volume by measuring the gas that metal and appropriate acid reaction are released of providing, thus try to achieve quality and the massfraction of oxidized metal.
