Ntawm no yog ib daim ntawv teev cov feem ntau muaj zog bases

Lithium roj teeb hydroxide .
NaOH - sodium hydroxide .
KOH - poov tshuaj hydroxide .
RbOH - rubidium hydroxide .
CsOH - cesium hydroxide .
*Ca( OH )₂ - calcium hydroxide .
* Sr (OH )₂ - strontium hydroxide .
* Ba(OH )₂ - barium hydroxide .

Nyob rau hauv kev hwm rau qhov no, dab tsi yog lub hauv paus tsis muaj zog tshaj plaws?

Tsis muaj Acids & Bases

Common Weak Acids		Common Weak Bases
Trichloroacetic tshuaj	CCl3 COJ	pyridine
Hydrofluoric	HF	ammonium hydroxide
Hydrocyanic	HCN	dej
Hydrogen sulfide	H2S	HS- ib

Tsis tas li ntawd, 3 lub hauv paus tsis muaj zog yog dab tsi? 3 Lub hauv paus tsis muaj zog

NH3-Ammonia.
CH3NH2-Methylamine.
C5H5N-Pyridine.

Khaws qhov no hauv kev xav, dab tsi yog 7 lub zog acids thiab cov hauv paus?

Muaj 7 lub zog acids: chloric acid , hydrobromic acid , hydrochloric acid, hydroiodic acid , nitric acid, perchloric acid, thiab sulfuric acid. Ua ib feem ntawm cov npe ntawm cov kua qaub uas muaj zog tsis muaj qhov qhia txog qhov txaus ntshai lossis ua rau cov kua qaub puas.

Koj ua li cas thiaj paub tias lub hauv paus muaj zog lossis tsis muaj zog?

Qhov teeb meem zoo ib yam nrog hauv paus :ib lub hauv paus muaj zog yog a puag uas yog 100% ionized hauv kev daws. Yog tias nws tsawg dua 100% ionized hauv kev daws, nws yog tsis muaj zog puag . Muaj tsawg heev lub hauv paus muaj zog (saib Table 12.2” Muaj zog Acids thiab Bases ”); ib yam puag tsis teev yog ib tsis muaj zog puag.

Dab tsi yog lub hauv paus muaj zog tshaj ntawm pH nplai?

Cov hauv paus muaj zog muaj pH siab heev, feem ntau yog li 12 txog 14. Cov piv txwv zoo ntawm cov hauv paus muaj zog muaj xws li caustic soda lossis sodium hydroxide (NaOH), nrog rau lye lossis potassium hydroxide (KOH). Hydroxides ntawm alkali lossis Group 1 hlau yog feem ntau muaj zog hauv paus

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

Lub cheeb tsam dej hiav txwv twg muaj biodiversity loj tshaj plaws thiab lub neej dej hiav txwv tshaj plaws?

Epipelagic cheeb tsam nthuav tawm ntawm qhov chaw mus txog 200m nqes. Nws tau txais ntau lub hnub ci thiab yog li muaj cov biodiversity tshaj plaws nyob rau hauv dej hiav txwv. Nws tseem hu ua thaj tsam twilight vim tias lub teeb txwv tsis pub muaj peev xwm lim tau los ntawm cov dej no

Dab tsi yog qhov muaj zog tshaj plaws ntawm lub zog sib xyaw ua ke hauv nitrogen?

Kev piav qhia: Qhov muaj zog tshaj plaws ntawm cov npe shydrogen bonding. Hom kev quab yuam intermolecular no yog kev cuam tshuam uas tshwm sim ntawm hydrogen atoms thiab ib leeg khub onatoms ntawm oxygen, nitrogen thiab / lossis fluorine. Hydrogen bonds yog qhov muaj zog tshaj plaws thaum lub zog dispersion yog qhov qis tshaj
