Question

Use the modified Arrhenius theory to write a reaction equation for H2S(g) and SO2(g) to predict if it is acidic, basic, or neutral.

The H2S and SO2 are two different equations

Answer 1

Answer:

Historically, the first chemical definition of an acid and a base was put forward by Svante Arrhenius, a Swedish chemist, in 1884. An Arrhenius acid is a compound that increases the H+ ion concentration in aqueous solution. The H+ ion is just a bare proton, and it is rather clear that bare protons are not floating around in an aqueous solution. Instead, chemistry has defined the hydronium ion (H3O+) as the actual chemical species that represents an H+ ion. H+ ions and H3O+ ions are often considered interchangeable when writing chemical equations (although a properly balanced chemical equation should also include the additional H2O). Classic Arrhenius acids can be considered ionic compounds in which H+ is the cation. Table 12.1 “Some Arrhenius Acids” lists some Arrhenius acids and their names.

Formula Name

HC2H3O2 (also written CH3COOH) acetic acid

HClO3 chloric acid

HCl hydrochloric acid

HBr hydrobromic acid

HI hydriodic acid

HF hydrofluoric acid

HNO3 nitric acid

H2C2O4 oxalic acid

HClO4 perchloric acid

H3PO4 phosphoric acid

H2SO4 sulfuric acid

H2SO3 sulfurous acid

An Arrhenius base is a compound that increases the OH− ion concentration in aqueous solution. Ionic compounds of the OH− ion are classic Arrhenius bases.
