1. Raws li seb lawv yog cov organic lossis inorganic, cov kua qaub tau muab faib ua cov inorganic acids thiab cov organic acids.
Organic acids xa mus rau cov organic tebchaw uas nthuav tawm cov khoom acidic. Cov organic acids feem ntau yog carboxylic acids, uas nws acidity stems los ntawm pawg carboxyl (-COOH). Lwm cov tebchaw, xws li sulfonic acids (-SO₃H), kuj tau muab cais ua cov organic acids. Organic acids tuaj yeem cuam tshuam nrog cawv los ua esters.
2. Raws li qhov muaj lossis tsis muaj oxygen, cov kua qaub raug faib ua oxyacids thiab tsis yog -oxyacids.
Oxyacids (xws li sulfuric acid H₂SO₄, carbonic acid H₂CO₃, thiab lwm yam) thiab tsis yog -oxyacids (xws li, hydrochloric acid HCl, hydrofluoric acid HF, thiab lwm yam).
3. Raws li tus naj npawb ntawm H⁺ ions uas tuaj yeem sib cais los ntawm ib qho kua qaub molecule:
Cov kua qaub tuaj yeem faib ua monoprotic acids (xws li HCl), diprotic acids (piv txwv li, H₂SO₄), thiab triprotic acids (piv txwv li, H₃PO₄).
4. Raws li lawv cov txheeb ze acidity (lub zog)-tshwj xeeb, txawm tias lawv tau ua tiav kev sib cais-acids tau muab faib ua cov kua qaub muaj zog, cov kua qaub qis, thiab cov kua qaub tsis muaj zog.
Cov kua qaub muaj zog (piv txwv li, HCl), cov kua qaub muaj zog (piv txwv li, H₃PO₄), thiab tsis muaj zog acids (piv txwv li, H₂CO₃).
5. Raws li seb lub hauv paus atom tau txais electrons, cov kua qaub tau muab faib ua cov oxidizing acids thiab tsis yog - muaj zog oxidizing acids.
Muaj zog oxidizing acids (xws li, HNO₃).
