Uʻamea alkali

uʻamea Alkali - francium, cesium, rubidium, potassium, sodium, lithium - ina ia valaauina ona o faiga alkali e tali i le vai. Ona o le tomai maualuga e tali nei elemene e tatau ona teuina i lalo o se vaega o le suauu po o karasini minerale. Le o nei tuufaatasi e sili ona toaaga o loo manatu francium (o faʻaratiasia).

uʻamea Alkali - mea vaivai, lanu silvery. Latou faatoa vavae luga ua a luster uiga. ua liusuavai uʻamea Alkali ma maʻisua i le vevela maualalo, maua conductivity maualuga vevela ma le eletise. Latou te maua foi se density maualalo.

meatotino vailaau o uʻamea alkali

Mea o sui faaitiitia malosi, o le tuufaatasi faaalia se tikeri o le oxidation (tulaga ese) +1. Faatasi ai ma le faateleina o le atomika mamafa uʻamea alkali ma faateleina faaitiitia tomai. Toeitiiti lava o soluble le tuufaatasi o mea uma i le vai, ua latou ionic i le natura.

Ma faʻavevela feololo uʻamea alkali mumu i totonu o le ea. I le galulue faatasi ai ma le hydrogen fausia masima-e pei hydrides mea. e masani lava o oloa Combustion peroxides.

oxides Alkali uamea e solids samasama (oxides o rubidium ma potassium), sinasina (oxides o sodium ma lithium) ma moli (oxide Cesium) lanu. O nei oxides e mafai ona tali atu i le vai, acids, okesene, acid ma oxides amphoteric. O nei uiga faavae e fananau mai i latou uma ma ua i ai se uiga faaleoina.

peroxides o uʻamea alkali - efuefu lanu samasama-papae. O i latou o mafai ona tali atu i le carbon karaponi ma kasa monoxide carbon, acids, nonmetals, vai.

hydroxides uamea alkali e soluble i le vai, solids paepae. I nei tuufaatasi o loo faaalia (pupula lava) meatotino faavae alkalis. faamamaluina faavae Lithium e Franz ma tikeri o le solubility faateleina vai. manatu Hydroxides electrolytes lava malosi. Latou tali atu ma le masima, hydroxides amphoteric ma oxides, nisi lē uʻamea, oxides acid. Vagana lotoa ma isi lithium faaalia mautu vevela. Calcining hydroxide lithium o lona decomposition i le vai ma le oxide. Fai mai tuufaatasi e maua e ala i electrolysis fofo o faafitauli aqueous chloride o le tele o tali metabolic. saunia Hydroxides foi i le tali vaega (po oxides) ma le vai.

Toeitiiti lava masima uma faamatalaina uʻamea (ae vagana ai mo masima nisi lithium) e soluble i le vai lelei. Faia e acids vaivai, fofo saline maua se auala tali (alkaline) ona o hydrolysis o le masima faia le hydrolyzed ua pei acids malosi. masima Masani o maa (sodium) masima, a pipiʻi silicate (vai tioata), potassium nitrate, bertoletova masima, potassium permanganate, fefete fagu, fefete lefulefu, ma isi.

o le tuufaatasi alkali uma le tomai e sui ai le lanu o le mumu. E faaaogaina i le iloiloga vailaau. O lea, Ulaula pisia carmine afi ma ions lithium, i Vaioleti - ions potassium i samasama - sodium piniki whitish - rubidium, Vaioleti-mumu - cesium.

Ona o le mea moni e faapea sela alkaline uma o le sui faaitiitia sili ona malosi, e mafai ona latou maua le masima uʻamea e electrolysis.

Faaaogaina o uamea alkali

O le o loo faaaogaina elemene i le lalolagi i le ese o gaoioiga o le tagata. Mo se faataitaiga, o loo faaaogaina cesium i sela photoelectric. O le tuuina atu o loo faaaogaina uʻamea filogia o vaega taua lithium. Sodium o le taimi nei i le lamepa kesi-faataunuuina, reactors faaniukilia o se coolant. ua faaaogaina le gaoioiga e suesuega rubidium.
