純粋な次亜塩素酸溶液の作り方

2020-03-26View Original

Thread Content

塩素ガスが水に溶けると塩酸と次亜塩素酸の混合溶液ができますが、塩酸を除去して純粋な次亜塩素酸溶液を作るにはどうすればよいのでしょうか?電解混合溶液はいけますか?塩酸と次亜塩素酸の混合溶液を電解すると、どのような反応が起こるのでしょうか?

炭酸カルシウム粉末を含む水に塩素ガスを通すと、次亜塩酸が溶液中に蓄積される。反応混合物を蒸留することで、希薄な次亜塩酸溶液を回収することができる。 2H₂O + 2Cl₂ + CaCO₃ ----------> CaCl₂ + H₂O + CO₂↑ + 2HClO

蒸留は次亜塩素酸を分解しないのでしょうか?
