Magnesite, as noted above, is the name of a mineral, the composition of which is magnesium carbonate.
It may also contain calcium and magnesium carbonate and mineral jelly.
Limestone containing smaller amounts of magnesium carbonate is known as dolomitic limestone.
Part are carried in solution, as for example lime carbonate and magnesium carbonate, which go to make up limestone and dolomite.
Magnesium is an element, and is found in magnesium carbonate, a compound that is effective in correcting soil acidity.
If the acid is neutralized by the addition of an alkali—calcium or magnesium carbonate is best—then the sugar may all be split up.
In one form the jelly is impregnated with needles of magnesium carbonate (Schaudinn), but these are absent in the other form.
Like calcium carbonate, magnesium carbonate is insoluble in water, though easily dissolved by acids.
