Barium hydroxide. It is produced by dissolving barium oxide obtained by thermal decomposition of barium carbonate in hot water and cooling it. It can also be produced by the double decomposition of barium chloride and sodium hydroxide. BaCl 2 +2NaOH―→Ba(OH) 2 +2NaCl Ba(OH) 2 +CO 2 ―→BaCO 3 +H 2 O [Torii Yasuo] [Supplementary Materials] | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
