Silver iodide yog ib qho inorganic compound nrog rau cov qauv AgI. Lub compound yog lub teeb daj daj, tab sis feem ntau ib txwm muaj impurities ntawm hlau nyiaj uas muab ib qho xim grey. Cov nyiaj Cov kab mob kis tau tshwm sim vim AgI yog cov photosensitive heev. Cov cuab yeej no yog exploited hauv nyiaj -raws li kev yees duab.
Ntxiv rau qhov no, AgI yog dab tsi hauv chemistry?
Silver iodide yog ib qho inorganic compound uas yog highlyphotosensitive (reacts thaum raug lub teeb). Nws yog hu ua iodide lossis iodargyrite. Formula andstructure: Cov tshuaj formula ntawm silver iodide yog AgI thiab nws qhov hnyav yog 234.77 g / mol.
Ib yam li ntawd, nyiaj iodide ua li cas rau tib neeg lub cev? Tshaj tawm rau qib siab ntawm nyiaj lub sijhawm dhau mus ua tau ua rau grey orblue-greydiscoloration ntawm daim tawv nqaij thiab lwm yam ntaub so ntswg hu ua asargyria. Thaum qhov xwm txheej no nyob mus ib txhis, nws xav tias tsuas yog teeb meem beacosmetic uas tsis muaj kev phom sij rau kev noj qab haus huv (ATSDR, 1990; ATSDR, 1999).
Tsuas yog li ntawd, AgI yog xim dab tsi?
Kev sib tham:
| Precipitate | Xim | Ksp |
|---|---|---|
| AGOH | xim av | 6.8 x 10-9 |
| AgCl | dawb | 1.8 x 10-10 |
| AgBr | daj | 7.7 x 10-13 |
| AgI | daj | 8.3 x 10-16 |
Puas yog silver iodide soluble hauv dej?
nyiaj tshuaj chloride Nyiaj fluoride, AgF, formscolorlesscubiccrystals; nws yog ntau dua soluble nyob rau hauv dej dua lwm tus nyiaj halides.

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog txhais los ntawm lo lus inorganic hauv lub ntsiab lus ntawm cov ntxhia?
Ib txwm tshwm sim, homogeneous inorganic khoom muaj cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv crystalline qauv, xim, thiab hardness. Ib qho khoom siv tsis zoo, xws li calcium, hlau, potassium, sodium, lossis zinc, uas yog qhov tseem ceeb rau kev noj haus ntawm tib neeg, tsiaj txhu, thiab nroj tsuag
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
