Can sodium carbonate, sodium hydroxide and sodium chloride produce the same product in one or two steps?
Thread Content
We have a mixture of sodium carbonate, sodium hydroxide and sodium chloride. Sodium hydroxide accounts for 5%, sodium carbonate accounts for 35%, and sodium chloride accounts for 60%. This mixture is very troublesome to use the combined alkali method and the carbonization method. Can some substance be added to make sodium hydroxide, sodium carbonate and sodium chloride form the same product, thus eliminating the trouble of separation? Think about it and see what kind of product can use these three as raw materials.
Adding hydrochloric acid and sodium hydroxide produces sodium chloride and sodium carbonate produces sodium chloride and carbon dioxide. Does this idea work?

The remaining sodium chloride can continue to be used to generate soda ash
Can even sodium chloride react, or is it using a certain characteristic of sodium metabisulfite and sodium chloride to achieve separation?
Adding any kind of dirty material will directly generate one product, that is, waste product
