NaCl yog a tsis muaj zog base than NaOH. Muaj zog kua qaub react nrog lub hauv paus muaj zog rau daim ntawv tsis muaj zog acids thiab bases.
Ib sab ntawm no, NaCl puas muaj zog lossis tsis muaj zog?
Classifying Electrolytes
| Muaj zog Electrolytes | muaj zog acids | HCl, HBr, HI, HNO3, HClO3, HClO4, thiab H2YOG4 |
|---|---|---|
| lub hauv paus muaj zog | NaOH, KOH, LiOH, Ba(OH)2, thiab Ca(OH)2 | |
| ntsev | NaCl, KBr, MgCl2, thiab ntau, ntau ntxiv | |
| Electrolytes tsis muaj zog | ||
| tsis muaj zog acids | HF, HC2H3O2 (acetic acid), H2CO3 (carbonic acid), H3PO4 (phosphoric acid), thiab lwm yam |
Qhov thib ob, NaCl puas yog cov kua qaub lossis lub hauv paus lossis nruab nrab? Sodium chloride , uas yog tau los ntawm neutralization ntawm hydrochloric kua qaub thiab sodium hydroxide, yog a nruab nrab ntsev. Neutralization ntawm tej yam muaj zog kua qaub nrog lub zog puag ib txwm muab ib nruab nrab ntsev.
Ua qhov no hauv kev txiav txim siab, NaCl puas yog kua qaub?
NaCl yog tsim los ntawm cov tshuaj tiv thaiv ntawm HCl thiab NaOH. Ob leeg muaj zog kua qaub thiab bases. Thaum muaj zog kua qaub thiab lub hauv paus muaj zog react ua ke lub resultant yog ntsev thiab dej. Yog li ntawd NaCl yog ntsev.
Yog vim li cas NaCl yog acidic ntsev?
Cov ntsev nws tus kheej tsis yog acidic . Qhov no yog vim li cas hauv dej, NaCl dissociates rau Na+ thiab Cl-. Na + yuav sib txuas nrog hydrogen thiab oxygen los tsim NaOH, lossis sodium hydroxide, lub hauv paus muaj zog, thaum Cl- yuav tsim HCl, lossis hydrochloric kua qaub ,ib zog kua qaub.

Puas yog HClO muaj zog lossis tsis muaj zog?
HClO yog ib qho kua qaub raws li nws muaj cov proton uas nws tso tawm tab sis nws yog ib qho tsis muaj zog acid vim nws tsis yog ib qho acidamoung cov npe ntawm cov kua qaub muaj zog
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Puas muaj zog acid thiab qaug zog hauv paus ua rau tsis muaj?
Raws li koj tau pom hauv kev suav cov pH ntawm cov kev daws teeb meem, tsuas yog ib qho me me ntawm cov kua qaub uas muaj zog heev yog qhov tsim nyog los hloov pH. Ib qho tsis yog tsuas yog sib xyaw ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate lossis lub hauv paus tsis muaj zog thiab nws cov conjugate acid. Buffers ua hauj lwm los ntawm reacting nrog ib qho ntxiv acid los yog hauv paus tswj pH
Thaum twg muaj zog acid yog titrated nrog lub hauv paus tsis muaj zog?
Titration ntawm lub hauv paus tsis muaj zog nrog lub zog acid. Nyob rau hauv ib qho tsis muaj zog hauv paus-muaj zog acid titration, cov kua qaub thiab lub hauv paus yuav hnov mob los tsim cov kua qaub. Lub conjugate acid yuav raug tsim thaum lub sij hawm titration, uas tom qab ntawd reacts nrog dej los tsim hydronium ions. Qhov no ua rau muaj kev daws teeb meem nrog pH qis dua 7
Dab tsi ua rau acid tsis muaj zog lossis muaj zog?
Cov kua qaub tsis muaj zog yog cov kua qaub uas ib nrab dissociates rau hauv nws cov ions hauv cov kua dej los yog dej. Nyob rau hauv sib piv, ib tug muaj zog acid tag nrho dissociates rau hauv nws ions nyob rau hauv dej. Nyob rau tib lub ntsiab lus, cov kua qaub tsis muaj zog muaj pH ntau dua li cov kua qaub muaj zog
