This conversion is part of the causticizing step in the Kraft process for making pulp.[8] In the causticizing operation, burned lime is added to green liquor, which is a solution primarily of sodium carbonate and sodium sulfate produced by dissolving smelt, which is the mo...
Sodium carbonate is anorganic sodium saltand a carbonate salt. Why is NaHSO3 an acidic salt? Neither K+ nor ClO4- has any tendency to donate or accept a proton in dilute aqueous solutions. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. (c) Potassium hydr...
