Ammonium carbonate + CaO has high basicity after calcination?

  • Thread starter LimHua
  • Start date
Recently, I read one paper stated that dip CaO into Ammonium carbonate solution and calcined the mixture at high temperature after stirring for 30 minutes can give high basicity to CaO, how does it work?

Ammonium carbonate and calcium oxide in water will produce a solution of suspended calcium carbonate and ammonium hydroxide. Calcine that and you’re back to calcium oxide. The ammonium hydroxide is lost during the drying/heating/calcining process.

If it is back to Calcium oxide, why inside the article stated that the basicity increased? I don’t understand why the basicity increased since it just go back to the original state

Pretty difficult to get more basic than calcium oxide. That stuff will melt your face!
