Acid is a molecule capable of donating proton or forming covalent bond with electron pair. Arrhenius acids increase H+ concentration in water, forming hydronium ion H3O+. Brønsted-Lowry acids donate protons to bases, Lewis acids accept electron pairs
Colorless and odorless inorganic compound with formula H4P2O7. Soluble in water, diethyl ether, and ethyl alcohol. Crystallizes in two polymorphs melting at 54.3 and 71.5 °C. Contains four distinct pKa values in two distinct ranges
Hydrochloric acid is a colorless solution of hydrogen chloride. It is classified as a strong acid with a pungent smell. The pKa value in aqueous solution is approximately -5.9
Strong acids completely dissociate in water to form hydrogen ions. There are seven common strong acids: HCl, HNO3, H2SO4, HBr, HI, HClO4, HClO3. Strong acids have high Ka or small pKa values
