Sulfuric Acid

Sulfuric Acid Sulphuric acid; H2SO4 = 98.08 (7664-93-9)

When no molarity is indicated use analytical reagent grade of commerce containing about 96% w/w of sulfuric acid and about 18m in strength; an oily, corrosive liquid; weight per mL, about 1.84 g.

When solutions of molarity xm are required, they should be prepared by carefully adding 54x mL of sulfuric acid to an equal volume of water and diluting to 1000 mL with water.

When 'sulfuric acid' is followed by a percentage figure, an instruction to add, carefully, sulfuric acid to water to produce the specified percentage v/v (or, if required, w/w) proportion of sulfuric acid is implied.
