The method for mixing sulphuric acid with water is carried out by supply of acid and water into a common vessel, which is sulphuric acid absorber. Acid into the absorber will be given with the concentration, which is less than 98.3 %, through the distributing plates of absorber to the ...
Sulfuric acid is a very cheap and easy-to-get liquid, being commonly used for restoring exhausted car batteries and in the leather industry. Concentrated H2SO4 (52–100%, mixed in water) is also commonly used as a drain cleaner, and is easily available from various retail outlets. Consequen...

In addition to being an oxidizing agent, reacting readily at high temperatures with many metals, carbon, sulfur, and other substances, concentrated sulfuric acid is also a strong dehydrating agent, combining violently with water; in this capacity, it chars many organic materials, such as wood, ...
Dissolve heat concentrated sulfuric acid when dissolved emit a large amount of heat, so concentrated sulfuric acid dilution should be "acid into the water, along the wall, slow rewind, constantly stirring. "If the water into concentrated sulfuric acid, temperatures will hit 173 degrees centigrade,...
H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form. Many other concentrations, with different na...
