Looking at the name of an acid, how do you know if it only contains two
elements or if it contains more than two? PLEASE HELP.

Sagot :

Answer:

If it contains only 2 elements it will begin with “hydro” as in  

hydrochloric acid (HCl). If it contains more than 2 elements it is named based on the polyatomic (oxy) anion, as in nitric acid (HNO3), nitrous acid (HNO2), sulfuric acid (H2SO4). If the element has more than one possible charge, the value of the charge comes after the element name and before the word ion. Thus, Fe 2+ is the iron two ion, while Fe 3+ is the iron three ion.
