Abstract
The utility model provides a measurement device for gas production speed, includes gaseous generating device, characterized by: still including basin, scale test tube, glass return bend, and air guide hose, proper amount water is equipped with in the basin, the scale in vitro is filled with water and is put upside down in the basin, the air guide hose connection is between gaseous generating device and glass return bend, the elbow of the glass return bend other end stretches into the scale in vitro from the underwater to derive the gas that generates to the scale in vitro in the gaseous generating device, the new gaseous volume that generates is read to the scale from the scale test tube. The beneficial effects are that: coming tolerance to generate gaseous volume with the gaseous liquid volume of opening of arranging, can following the gaseous volume of direct readout on the scale test tube, easy operation is convenient, has avoided in original technique big, and the problem that easily drops of spare part of frictional resistance, the record used time of reaction, can measure the speed of reaction, volume or the concentration of reactant etc. Are changed, the factor of influence reaction speed can be studied.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, particularly a kind of measurement mechanism of gas generating rate.
Background technology
People teaches the chemistry of version to take as an elective course in 4, and arranging has measurement zinc and sulfuric acid reaction to generate the device of gas speed.The gas that this device generates with syringe collecting, utilizes the scale on syringe to read the amount generating hydrogen, the time that record reaction is used, thus can measure the speed of zinc and sulfuric acid reaction.This principle of device is simple and clear, but Problems existing is: the frictional resistance between the piston of syringe and urceolus is comparatively large, and the gas of generation is difficult to promote piston, and also cause the internal gas pressure of syringe constantly to change, the reliability of the gas volume value measured is low.After coating lubricating oil, energy reducing friction resistance, but its piston has the risk released by gas and come off damage.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is the measurement mechanism providing a kind of gas generating rate, require keeping measuring the volume generating gas under the substantially constant condition of gas pressure intensity, thus the accurate speed calculating gas and generate, compare the speed of chemical reaction.
The technical scheme that the utility model adopts is: a kind of measurement mechanism of gas generating rate, comprises gas generating unit, it is characterized in that: also include tank, scale test tube, glass bend pipe and soft air-guide pipe; Described tank is built with appropriate water, described scale is in vitro filled water and is put upside down in the sink, described soft air-guide pipe is connected between gas generating unit and glass bend pipe, the elbow of the described glass bend pipe other end stretches into scale in vitro from underwater, so that the gas generated in gas generating unit is exported to scale in vitro, read the volume of newly-generated gas from the scale scale test tube.
The beneficial effects of the utility model are: the liquid volume arranged with gas measures the amount generating gas, the volume of newly-generated gas can be read from the scale scale test tube, simple to operation, to avoid in original technology the large and caducous problem of parts of frictional resistance; The time that record reaction is used, the speed of reaction can be measured; The amount of change reactant or concentration etc., can study the factor of impact reaction speed.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation in a state of use;
In figure: 1 gas generating unit, 2 long neck funnels, 3 conical flasks, 4 soft air-guide pipes, 5 glass bend pipes, 6 scale test tubes, 7 tanks.
Embodiment
As shown in Figure 1, be existing gas generating unit 1 in dotted line frame, dotted line frame is outward structural representation of the present utility model.Gas generating unit 1 in figure is the device of common Chemistry Laboratory in Middle School hydrogen making, is placed with appropriate zinc granule, injects sulfuric acid downwards with long neck funnel, can react generation hydrogen in conical flask 3.
As shown in Figure 1, gas generating unit 1 is connected with glass bend pipe 5 by soft air-guide pipe 4, the elbow of the glass bend pipe other end (in Fig. 1 right-hand member) stretches in scale test tube 6 from underwater, the in-built full water of scale test tube 6 is also placed upside down in tank 7, tank 7 is built with appropriate water, with the gas with upwards drainage collection generation, and read the volume of newly-generated gas from the scale scale test tube.
Claims (1)
