Sodium sulfite is a 15% solution of sodium sulfite with the chemical formula Na 2 SO 3.. INEOS Calabrian is an on purpose Sodium Sulfite producer. Sodium sulfide is a sparingly-soluble salt. Na2S is produced by passing H2S gas through a sodium hydroxide solution until weak alkaline pH, followed by evaporation of water and crystallisation.H2S + 2NaOH --> Na2S … What is the pH of a 0.2M solution of Na2S?
