Problems solved by technology

[0002] In the chemistry class of junior high school, when doing the experiment of hydrogen and copper oxide, the hydrogen and the agent collected in advance were used. Due to too many joints, the sealing performance was naturally poor, resulting in poor experimental results and the phenomenon was not obvious. Aspects of knowledge are difficult to master

Embodiment Construction

[0006] The present invention is further described below in conjunction with embodiment with reference to accompanying drawing:

[0007] The present invention is a glass article.

[0008] The invention is composed of a test tube (1), an air guide tube (3) and a conical flat-bottomed flask (4). A test tube stopper (2) is attached to the test tube, and the test tube is obliquely connected with the airway. A flask stopper (5) is attached to the top of the conical flat-bottomed flask, and a drain pipe (6) with a stopper (7) is provided below. Use the hydrogen (Zn+H2SO4=H2↑+ZnSO4) generated by the reaction of zinc particles and acid in the test tube (1) to directly remove the copper oxide, and it can be visually seen that the black copper oxide slowly turns into red copper (H2 +CuO=Cu+H2O), the water generated during the reduction process is discharged from the drain.

Abstract

The invention relates to a device for reduction of copper oxide by hydrogen. The device is made of glass and composed of a test tube (1), a gas guide tube (3) and a taper flat bottom flask (4) in a connection mode. A test tube plug (2) is attached to the test tube, and the test tube is obliquely connected with the gas guide pipe. A flask plug (5) is attached to the upper portion of the taper flat bottom flask, and a water discharging pipe (6) with a pipe plug (7) is arranged on the lower portion of the taper flat bottom flask. Hydrogen (Zn+H2SO4=H2+ZnSO4) generated by the reaction of zinc granules and acid in the test tube (1) is directly used for reducing the copper oxide, and it can be visually seen that the black copper oxide slowly changes into red copper (H2+CuO=Cu+H2O), and water generated in the reduction process is discharged out of a water discharge pipe.

Description

technical field [0001] The invention relates to a chemical instrument, in particular to a device for reducing copper oxide with hydrogen. Background technique [0002] In the chemistry class of junior high school, when doing the experiment of hydrogen and copper oxide, the hydrogen and the agent collected in advance were used. Due to too many joints, the sealing performance was naturally poor, resulting in poor experimental results and the phenomenon was not obvious. Aspect knowledge is difficult to grasp. Contents of the invention [0003] The present invention is a glass article. The invention is composed of a test tube (1), an air guide tube (3) and a conical flat-bottomed flask (4). A test tube stopper (2) is attached to the test tube, and the test tube is obliquely connected with the airway. A flask stopper (5) is attached to the top of the conical flat-bottomed flask, and a drain pipe (6) with a stopper (7) is provided below. Use the hydrogen (Zn+H2SO4=H2↑+ZnSO4)...
