Question: Identify each of the following as an acid or base and write a chemical equation showing how it is an acid or a base according to the Arrhenius definition?
a.) HNO3
b.) NH4+
c.) KOH
d.) HC2H3O2
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs.
assign oxidation numbers to all the elements in each of the following compounds or polyatomic ions: a)C2H3O2^- b)AlCl3 c)NH4^+ d)HBrO4
