Naming Acids

By Grant S (quizlet at the bottom)

Intro to naming acids

Before getting right into the process of creating names for acids, you must first understand what all the conditions are for making a name. Once you have all of these memorized, it will help you formulate acid names so quickly it'll come to you as fast as the answer to 2+2. Below is the list of crusial things that you must know before proceeding any further in the learning process.

Acid naming keys to success

  • All names for acids end with the word "acid," and you can see an example of this in the picture below.
  • Acids names are based upon their anion, the one that is put with the hydrogen cation.
  • In binary acids, the prefix "hydro-" is applied to the name and the suffix "-ic" is applied to the anion.
  • For acids with a polyatomic ion, the suffix changes to "-ate."
  • If a polyatomic ion has an extra oxygen, then the prefix "per-" will be applied, alongside the suffix "-ic."
  • When a polyatomic ion, however, has one fewer oxygen, it will have the suffix "-ous" applied.
  • Finally, If a polyatomic ion has two fewer oxygen, then the prefix "hypo-" will be placed on with the suffix "-ous."

Naming the acids

Like naming any compound molecule, you have a cation and an anion, in that order. However, with acids, the cation will always be hydrogen. Meaning that with acids, you actually have Hydrogen and an anion. Where the anion usually has the suffix "-ide," whereas with acids this suffix is changed to "-ic" and there prefix "hydro-" is applied (the prefix does not apply to polyatomic ions).
