Transformations of manganese ethylenediamine tetraacetates under action of acids and bases

Бесплатный доступ

An aqueous suspension of manganese(II) bis (ethylenediaminetetraacetate manganate) decahydrate under action of bases (sodium hydrogen carbonate, lithium hydroxide, and ammonia) dissolves at pH = 8, turning into well- known freely soluble compounds of sodium, lithium, and ammonium tetraacetate manganates. The interaction of manganese(II) bis (ethylenediaminetetraacetate manganate) with 2-aminoethanol, which also creates a weakly alkaline medium, proceeds in a similar way. In acidic medium at pH = 1 sodium, lithium, ammonium, and 2-aminium ethanol tetraacetate manganates are converted into manganese(II) bis (ethylenediaminetetraacetate manganate). Manganese(II) (ethylenediaminetetraacetate manganate) trihydrate, when acidified with sulfuric acid, turns into manganese(II) bis (ethylenediaminetetraacetate manganate).
