Manganese(II) sulfate is the sulfate salt of manganese, with the formula MnSO4. Although the anhydrous salt is white, its hydrates are pinkish in color.
Contents
Properties
Chemical
Manganese(II) sulfate will precipitate as manganese hydroxide when mixed with a strong base, such as sodium hydroxide.
Physical
Manganese sulfate is a pinkish crystalline salt, soluble in water, as well as primary alcohols, though insoluble in aprotic solvents, such as benzene or diethyl ether. It is most often encountered as monohydrate form, though other hydrates, like tetrahydrate, pentahydrate, and heptahydrate also exist.
Availability
Manganese sulfate is sold by various chemical suppliers.
Preparation
There are a few ways to make manganese(II) sulfate.
One involves the direct reaction of sulfuric acid with manganese metal:
- H2SO4 + Mn → MnSO4 + H2
This reaction however, does not work with manganese dioxide, which is more available that manganese metal. There are a few ways around though:
One way is to react manganese dioxide with oxalic acid and then react the resulting manganese oxalate/carbonate with sulfuric acid.
Another method involves bubbling sulfur dioxide through a suspension of manganese dioxide in water, and the filtering the solution.
- MnO2 + SO2 → MnSO4
You can also dissolve manganese alloys in sulfuric acid, however the resulting manganese sulfate will be contaminated with iron sulfate as well as other sulfates.
Projects
- Make very pure manganese dioxide
