Respiration of plants is very important, and the determination of their strength needs to be rigorously tested. In order to be able to better measure the breathing intensity of the plant, the respiratory intensity of the plant can be measured by the small basket method. When titrating with oxalic acid, the buret should be inserted into the titration well on the wide-mouth bottle stopper. The plant respiration measurement system can be used to determine the respiration of plants.

Because in the titration process, the need to constantly shake the jar, often cause the buret tip to break or break, and sometimes students in order to avoid this phenomenon occurs, simply titrate when the buret is not close to the titration hole, this will appear in the tube oxalic acid Loss and outside air from the hole into the jar cause experimental errors or failures.
A small improvement was made to the experimental device: Take a soft plastic tube (or rubber tube) with a slightly smaller caliber than the titration hole on the stopper, insert the lower end of the tube into the titration well, seal it with petrolatum paste, and titrate before Can be clamped with iron clips. Remove the clamp during the titration and insert the burette into the plastic tube so that when the jar is shaken, the burette will not be damaged, and the titrant will not be lost. Because the seal is in good condition, the outside air is not easy to enter into the jar to ensure the experiment. The accuracy is correct. Using plant respiration measurement systems to measure plant respiration can more accurately draw relevant conclusions.
