I have searched many forms for information about the soda lime process for making sodium hydroxide.  I haven't much though. The reaction is Na2Co3 + Ca(OH)2--> 2NaOH + CaCo3
Apparently this reaction deals with the calcium carbonate precipitating out.  Well, I bought some pickling lime and pH increaser making sure each was Sodium carbonate and Calcium hydroxide. So, will this reaction work? If so then how? I tried myself and tested the solution for NaOH by putting a little aluminum foil in and nothing happended which makes me think I did something wrong.  Does anyone know the amounts used to make this reaction efficient? Thanks in advance as always.
