铋酸钠制备

1.将干燥的三氧化二铋与其质量1/2的过氧化钠混合，在隔绝湿气及二氧化碳的空气中加热。首先迅速加热至350℃，以后慢慢加热至600℃，直到气体的发生结束。冷却后，应确认即使往其中加水，也不再产生气体。反应才算完成。实验中最好使用熔结氧化镁制的坩埚。

2.将试剂级硝酸铋溶解于稀硝酸溶液中，滤去不溶物之后，依次加入水和30%的工业级氢氧化钠溶液，至溶液对刚果红指示剂呈中性为止。然后再依次加入30%的氢氧化钠溶液和含有效氯不低于70g/L的次氯酸钠水溶液，进行氧化反应：

反应需加热至95℃并维持1h。反应结束后，静置冷却，分去上层清液，用水洗涤沉淀至洗液中不含Cl^-子，然后在80℃下干燥，即为成品。
