Diaphragm Electrolyzer Electrolytic Saturated Saline Chemical
Instrument Teaching Instrument for Hydrogen Production Unit
Size:10*8*12 cm
Vertical Diaphragm Electrolyzer Demonstrator
Purpose:
Hydrogen and chlorine are produced from electrolytically saturated saline solution.
1. Electrolytically saturated salt water (1)
The saturated salt water is prepared with hot water at 60-70 C, and then it is transferred to the electrolyzer.
Two-thirds of the saturated salt water
was injected into the medium, and two gas-collecting bamboos were
filled with saturated salt water.
Salt water is inserted into two
electrodes (two drops of phenolphthalein solution are dripped into the
catheter on the negative electrode) and DC power supply shall not be
less than 24V.
Then pay attention to the phenomenon
in the tube. After about three minutes, remove the catheter on the
negative pole, block the small hole with the thumb, move close to the
flame, loosen the thumb, remove the catheter on the positive pole, and
quickly close the wet potassium iodide starch test paper to the small
hole to observe the phenomenon. .
2. Electrolytically saturated salt water (2)
Using combustion method to test
chlorine gas, the operation steps are basically the same as those
mentioned above. The specific operation is as follows:
Insert a bottomless hard test tube
with a diameter of 20 mm on the positive pole, wrap a small amount of
red phosphorus powder around two matchsticks with cotton wire, tie the
matchstick with thin wire, try to let it hang in the test tube, turn on
the power supply, observe the phenomenon (spontaneous combustion after 2
minutes)
Notes: After the demonstration I, pour
out the electrolyte and clean it so as not to detain the solution and
corrode the zinc plate.
