oleaginous fluid tinged with yellow, odorless. Mixes with water in all proportions, the reaction is accompanied by evolution of large amount of heat.

Physicochemical parameters:

Sulfuric acid – oily liquid of yellowish color. No odor, almost twice as heavy as water. Mixed with water in any ratio, reaction is accompanied with heat release.

Physical properties of sulfuric acid depend upon mass fraction of basic substance.

Density and boiling temperature of aqueous solutions increase as the mass fraction of sulfuric acid increases and reach maximum value at mass fraction of sulfuric acid of 98.3%, decreasing thereafter.

Mass fraction of monohydrate (Н2S04), %, min    92.5
Mass fraction of ferrum (Fe), %, max  0,1
