Sodium hydroxide and metals clorides from salt using polypropylene diaphragm
This is a test diapragm from this topic
https://www.sciencemadness.org/whisper/viewthread.php?tid=16...
About 330 grams of sodium chloride dissolved in 2 liters of water. Solution was poured into a 5 -liter polypropylene container and a diaphragm made
as written in the topic about diaphragms. Cathode solution was diluted to equalize fluid levels
Anode is iron scrap. Cathode stainless steel from the hose from the shower. Voltage 5 volts. Current 1a. At the end of the electrolysis, it fell to
0.8 amperes. Electrolysis time 6 days
Diaphragm was quickly extracted from the electrolyzer to prevent leakage.
Diaphragm was clogged with iron hydroxide, but then washed with acid. This did not have effect on conductivity
Cathode solution was filter and was evaporated to a density of 1.3. About 70 grams of salt fell in the precipitate. 270 ml of alkali solution of about
30% was obtained. About 100 grams of sodium sodium hydroxide total
Anode solution was also filtered and evaporated. In the process of evaporation, hydrolysis and corroding of metal containers occurs. After drying, 230
grams of wet crystals were obtained. Iron chloride 2 is highly polluted by sodium chloride by this results preliminary. Also, iron chloride is
oxidized in the air
Iron chloride 2 has little value, but can be used to prepare iron benzoats and obtaining, for example, acetophenone
Other chlorides can be prompted in the same way. For example, zinc chloride. The method does not require acids and gives a side alkali.
You can also get chlorine
In the process of electrolysis, there were no damage to the diaphragm. This can work for a very long time
