Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".
By having more than one anion, many more compounds can be made, and properties tuned to desirable values. [3] In terms of optics, properties include phosphorescence, photocatalysis, [4] laser damage threshold, refractive index, birefringence, absorption particularly in the ultraviolet or near infrared, non-linearity. [5]
The name of the cation (the unmodified element name for monatomic cations) comes first, followed by the name of the anion. [ 100 ] [ 101 ] For example, MgCl 2 is named magnesium chloride , and Na 2 SO 4 is named sodium sulfate ( SO 2−

It was the precursor to today's more commonly used baking powder. Originally made from ground deer horn and called hartshorn, today it is called baker's ammonia. It is prepared by the sublimation of a mixture of ammonium sulfate and calcium carbonate and occurs as a white powder or a hard, white or translucent mass. [4]
