Manganese oxalate

Preparation of Manganese(ll) Oxide. Dehydrate 1 g of manganese oxalate by heating in a porcelain bowl at not over 200 °C. Transfer the salt into a porcelain boat and roast it in a tubular furnace in a stream of dry hydrogen at 300-400 °C (see Fig. 115). Preliminarily check the tightness of the apparatus and the purity of the hydrogen ...

In the case of the dehydration reactions, a particular form was announced by Smith-Topley for the influence of the water vapor on the dehydration of manganese oxalate dihydrate [TOP 35] and was found thereafter in other cases by various authors.

It seems that we can explain this effect, in all the cases, by a modification of the equilibrium constant (i.e. dissociation pressure of the hydrate) with the water pressure applied even if this modification does not always come from the same cause. Indeed, this variation of equilibrium constant can We at least two causes. With the first one, we eiqilain the effect on copper sulfate and with the other one the effect on lithium sulfate or manganese oxalate.
