The concern is that if water remains in the lines when sulphuric acid is introduced, there may be a violent reaction due to the sudden mixing of water and acid.See all results for this questionsp.info Standard Operating ProcedureNov 09, 2012 · Sulfuric acid, also spelled sulphuric acid, is a highly corrosive mineral acid. Its corrosiveness on metals, stones, skin, eyes and flesh and other materials can be mainly ascribed to its strong acidic nature and if concentrated strong dehydrating property and strong oxidizing property. The historical name of this acid is oil of vitriol.

Concentrated Sulfuric Acid - Inyo Process

Concentrated sulfuric acid (93%-98%) is an oily liquid with a density nearly twice that of water and a viscosity similar to honey.Sulfuric acid typically requires additional diffusion or mixing techniques to assure reliable diffusion into the process stream without damage to the process piping. If at all possible, it is best to predilute the acid down to 0.5%-3% concentration.(Acid dilution is discussed at the bottom of this page).See more on inyoprocess.com

Second, as sulfuric acid is diprotic, we could expect titration curve with two plateaux and two end points. However, that's not the case. Even if the se…See more on titrations.info

Forms of sulfuric acid
Although 100% sulfuric acid can be made, this loses SO3 at the boiling point to produce 98.3% acid. The 98% grade is also more stable for storage, making it the usual form for "concentrated" sulfuric acid. Other concentrations of sulfuric acid are used for different purposes. Some common concentrations are: 1. 10…Polarity and conductivity
Anhydrous H2SO4 is a very polar liquid, with a dielectric constant of around 100. This is due to the fact that it can dissociate by protonating itself, a process known as autoprotolysis, which occurs to a high degree, more than 10 billion times the level seen in water: 1. 2 H2SO4 ⇌ H3SO4+ + HSO4− This allow…See more on cs.mcgill.ca
