Acid ions refer to anions produced when an acid is ionized.
Acid roots are generally divided into strong acid roots and weak acid roots. The former includes sulfate, hydrochloride, nitrate, etc., which are basically inorganic acids. The latter include carbonate, acetate, oxalic acid.
Roots, etc., except for carbonate, are basically organic acids.
Precautions for identification:
When using a reagent to identify multiple substances, the reagent selected must be able to react with most of the substances to be identified, and can produce different experimental phenomena. Commonly used identification reagents include FeCl3 solution, NaOH solution, Na2CO3 solution, dilute H2SO4, Cu(OH)2 suspension, etc.
The use of other reagents to identify a group of substances generally comes from two perspectives:
Using the special properties of some substances (such as color, odor, solubility, etc.), first identify, and then use the reagent to identify other substances.
The phenomenon of reacting with other substances is different from that of a reagent, and a comprehensive analysis is carried out to identify it.

Acidification with hydrochloric acid (no precipitation means no silver ions, no gas release means no sulfite and carbonate), and then add BaCl2 solution, if there is precipitation, it proves that there is sulfate.
Add BaCl2 to the solution, if there is a precipitate, it means that there are sulfate ions or carbonate ions in the original solution (because barium ions will form a precipitate when they encounter these two ions), and then add hydrochloric acid, if there is no change, it means that there are sulfate ions in the original solution, and if bubbles occur, it means that it is carbonate ions.
