Cov kua qaub muaj zog thiab pH
pH yog qhov ntsuas ntawm qhov concentration ntawm hydrogen ions hauv cov tshuaj. Cov kua qaub muaj zog xws li hydrochloric acidntawm cov kev sib xyaw uas koj ib txwm siv hauv chav kuaj muaj pH nyob ib ncig ntawm 0 txog 1. Qhov pH qis dua, qhov siab dua ntawm hydrogen ions hauv cov tshuaj.
Tus lej acid zog yog dab tsi?
Strong Acids
Feem ntau, cov kua qaub muaj zog muaj pH ntawm kwv yees xoom mus rau 3 . Qhov muaj zog cov kua qaub, qhov zoo dua nws dissociates nyob rau hauv ib tug aqueous tov, tso ntau cationic hydrogen (H+) ions. Piv txwv ntawm cov acids muaj zog muaj xws li hydrochloric acid (HCl), hydrobromic acid (HBr), perchloric acid (HClO 4), thiab sulfuric acid (H 2. SO4).
Dab tsi yog qhov tseem ceeb tshaj plaws?
