 note = {This report describes following chemical experiments in inorganic chemistry; 1. Formation and redissolution of precipitation in inorganic reaction. Reaction of calcium hydroxide with phosphoric acid was performed. White precipitation was formed with small amount of the acid. The precipitation was dissolved by adding more acid. Reaction of silver nitrate and ammonia solution was also performed. Formation and redissolution of precipitation was also observed in the reaction. 2. Synthesis and property of alum. Potassium alum was synthesized by reaction of aluminium sulfate and potassium sulfate. It was obtained as colorless crystal. Recrystallization of the alum was performed and large size crystal was obtained. Clarification of water was performed by using the alum as a coagulating agent. 3. Identification of white powdery substances. Following tests were performed for sodium chloride, sodium hydrogen carbonate, calcium carbonate, and calcium oxide. Solubility in water. Reaction with acid. Thermal change. These experiments are useful for students to understand basic inorganic chemistry., 本報では無機化学に関する化学実験について報告する．具体的なテーマは以下の通りである．1.　沈殿の生成と再溶解　水酸化カルシウムにリン酸との反応を行った．リン酸が少量の場合は，白色沈殿が生成した．さらにリン酸を加えることにより，沈殿は溶解して消失した．2.　ミョウバンの合成と性質　硫酸アルミニウムと硫酸カリウムとの反応により，カリウムミョウバンを合成した．得られたミョウバンは無色の結晶であった．この結晶は再結晶を行うことによって成長し，形の整った大きな結晶を得た．ミョウバンを凝集剤として用いた水の浄化も試みた．濁水にミョウバンを加えることによって溶けている物質が凝集し，無色透明の水を得た．3.　白色粉末の識別　塩化ナトリウム，炭酸水素ナトリウム，炭酸カルシウム，酸化カルシウムについて以下の実験を行い，比較した．水に対する溶解性．酸との反応．加熱による変化．これらの実験は，基礎的な無機化学の理解に役立と考えられる．},
