in the chloride, sulphate, carbonate, or silicate, in the minerals

Note: It is reduced from the carbonate as a soft white metal, lighter
than water, which oxidizes with the greatest readiness, and, to be

kerosene. Its compounds are very important, being used in glass
making, soap making, in fertilizers, and in many drugs and chemicals.
