Ib tug compound tej zaum yuav soluble yog hais tias nws muaj ib tug ntawm cov nram qab no anions:
- Halide: Cl -, Br -, kuv - (Tshwj tsis yog: Ag+, Hg2+, Pb2+)
- Nitrate (NO3-), perchlorate (ClO4-), acetate (CH3CO2-), sulfate (SO42-) (Tsuas: Ba2+, Hg22+, Pb2+ sulfates)
Tsuas yog li ntawd, cov anions feem ntau yog soluble hauv dej?
Cov Cai Solubility raws li Lub Rooj
| Txoj Cai Solubility rau Aqueous Solutions ntawm 25 ° C | ||
|---|---|---|
| Tsis zoo Ions (Anions) | + | Solubility ntawm compounds nyob rau hauv dej |
| chloride (Cl-) bromide (Br-iodide (ib-) | + | tsawg solubility (insoluble) |
| + | soluble | |
| sulfate (SO42-) | + | tsawg solubility (insoluble) |
dab tsi polyatomic ions ib txwm soluble? 1) Cov ntsev ammonium thiab alkali hlau (kem 1A tsis suav nrog hydrogen) yog ib txwm soluble. 2) Tag nrho cov chlorides, bromides, thiab iodides yog soluble tsuas yog thaum ua ke nrog Ag, Hg2+, thiab Pb uas yog insoluble. 3) Chlorates, acetates, thiab nitrates (CANs) yog soluble.
Tsis tas li ntawd, cov tebchaw twg yeej ib txwm soluble?
Cov Cai Solubility
- Cov ntsev uas muaj pawg I cov ntsiab lus (Li+, Na+, K+, Cs+, Rb+) yog soluble.
- Cov ntsev muaj nitrate ion (NO3-) feem ntau yog soluble.
- Cov ntsev muaj Cl -, Br -, los yog kuv - feem ntau yog soluble.
- Feem ntau silver ntsev yog insoluble.
- Feem ntau sulfate ntsev yog soluble.
- Feem ntau hydroxide ntsev tsuas yog me ntsis soluble.
Puas yog AgCl soluble hauv dej?
Muaj ntau ionic solids, xws li nyiaj chloride (AgCl) tsis yaj hauv dej. Cov rog tuav cov khoom AgCl lattice ua ke muaj zog dhau los ntawm cov rog uas nyiam tsim cov hydrated ions, Ag+(aq) thiab Cl-(aq).

Puas yog cov tebchaw uas tsim H + ions hauv kev daws?
Cov kua qaub yog cov tshuaj sib xyaw uas tso tawm hydrogen ions (H +) thaum muab tso rau hauv dej. Piv txwv li, thaum hydrogen chloride tso rau hauv dej, nws tso nws cov hydrogen ions thiab cov tshuaj ua hydrochloric acid. Bases yog cov tshuaj sib txuas uas nyiam hydrogen atoms thaum lawv muab tso rau hauv dej
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
