When the 2nd, using, the syringe thromboembolism 102 of syringe 1 is first pulled out, flexible pipe III 10 is clamped with clip III 1001, open folder
Son II 801, water are entered by flexible pipe II 8, and bottle II 5 is filled.During air storage, gas enters following bottle II 5, bottle II 5 by flexible pipe II 8
In water be pressed into bottle I 3 above, when the water almost all in following bottle II 5 is pressed into bottle I 3 above, illustrate bottle II
Gas is filled with 5, has been stopped ventilation, flexible pipe II 8 is clamped with clip II 801, be allowed to air tight, put the stand-by device well light
Flexibly, get up very convenient used in field research, as long as gas that is water insoluble or not reacting with water can all be used and is somebody's turn to do
Caisson is stored.
3rd, clip I 201, clip II 801, clip III 1001 are begun to shut off, alcohol burner 15 are placed on ethanol lamp-stand 1501,
Alcohol burner 15 is lighted, is first preheated to the horizontal segment of " u "-shaped pipe 11, then placing concentration heating at helical form thin copper wire, for a moment
Just see that the thin copper wire of redness becomes black, this is because the oxygen and copper wire in the air in " u "-shaped pipe 11 is in the bar being heated
Part issues raw combination reaction, generates the metal oxide copper of black.
4th, syringe thromboembolism 102 is inserted into 1 syringe of syringe, it is noted that in the syringe space reserved by certain capacity, is opened
Clip III 1001 and clip I 201, slow pushing syringe 1, while constantly mobile alcohol burner 15, so prevents alcohol burner 15 solid
It is scheduled at one and heats, the horizontal segment of " u "-shaped pipe 11 is burnt curved easily；With being slowly passed through for carbon monoxide, in " u "-shaped pipe 11
The lime water 12 of clarification is pressed to the vertical end of " u "-shaped pipe 11 by CO (carbon monoxide converter) gas, at this moment controls one by syringe thromboembolism 102
Carbonoxide is passed through speed, can be appreciated that the lime water of clarification gradually becomes muddy, and the copper wire of black gradually becomes redness, and effect is very bright
It is aobvious.
