Sulfuric Acid |

Sulfuric Acid. Sulfuric acid, H 2 SO 4, is a strong mineral acid, which is a viscous (thick and syrupy), oily liquid that has for years been the most widely used chemical in the found in a liquid state, sulfuric acid has a density of g/cm 3 and is soluble in water. Its melting point is about 50 ° F (10 ° C) and its boiling point is approximately 640 ° F (337 ° C).

Chemical Pretreatment For RO and NF

Technical grade sulfuric acid, with no other additives, is suitable for use with a RO. Sulfuric acid is commercially available as a 20% and 93% solution. The 93% solution is also referred to as “66 0 Baume solution”. Caution is required in diluting 93% sulfuric acid, since the maximum heat of dilution of about 280 F occurs around 60%.

What Are the Effects of Sulfuric Acid on Steel? (with picture)

Jan 13, 2020· With corroding steel, sulfuric acid often forms hydrogen gas, which furthers the corrosion. Low levels of hydrogen gas can cause the steel to groove or warp. The best reaction of sulfuric acid on steel is that the acid begins to create an iron sulfate layer that protects the steel from the acid and causes no corrosion and little metal loss.

High Silicon Cast Iron Sulphuric Acid

Corrosion rates of less than 5 mpy ( mm/y) are typical except in a region of hot acid from 5% to 55% H2SO4 where corrosion rates may be as high as 20 mpy ( mm/y). Above sulphuric acid, silicon cast iron is rapidly attacked by free SO3. One disadvantage of silicon cast iron is susceptible to thermal and mechanical shock.

AEROSIL® fumed silica in gel lead acid batteries

The gelling process of AEROSIL® fumed silica with sulfuric acid is characterized by the gel time and the gel hardness, which is measured as the penetration depth of a small metal ball into the silica/sulfuric acid mixture. As the viscosity of the gel increases with time the ball is slowed down and the penetration depth decreases [8, 9] (Fig. 10).
