Topic: Sulfuric Acid. Disscuss the stregth of the acid, its realtive conductivity, pH, stability of the negative anion (conjugate base), polarity of the acid, and stregth of the H-A bond for Sulfuric Acid.
stregth of the acid:
Sulfuric acid is a highly corrosive strong mineral acid with the molecular formula H2SO4.
Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4?). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42?). 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, paper, or sugar, leaving a carbonaceous residue.
its Polarity and realtive conductivity,
Anhydrous H2SO4 is a very polar liquid, having a dielectric constant of around 100. It has a high electrical conductivity, caused by dissociation through protonating itself, a process known as autoprotolysis.
2 H2SO4 H3SO+4 + HSO4?
The equilibrium constant for the autoprotolysis is
