關於alkalis 的問題

sodium carbonate is neither base nor alkali. A base is a compound which reacts with acid to form salt and water ONLY. An alkali is a base which is soluble.
Sodium carbonate reacts with acid to form carbon dioxide, water and salt, thus is not
alkali.

ammonia is alkali because ammonia react with water molecules to form hydroxide ions
and ammonium ions. It is the hydroxide ions which make the solution alkali.

sodium hydrocarbonate, similarly to sodium carbonate, is not alkali.

buddy above says sodium carbonate is an alkalii m sure it is not, because my chemistry text book says it is not.i dont think such a common text book would be wrongreference: Chemistry A Modern View - ARISTO

moreover, that reaction is not neutralization,for neutralization is a reaction between acid and base, giving salt and water ONLY
