Aluminium hlau yog ib txwm them rau hauv nyias, tab sis tiv thaiv txheej ntawm aluminium oxide, Al2O3. Cov tshuaj chloride ion pab cais cov aluminium los ntawm oxygen kom cov aluminium ua tau teb nrog rau tooj liab ions (thiab cov dej molecules).
Ua raws li qhov no hauv kev txiav txim siab, yuav ua li cas thaum aluminium reacts nrog tooj liab chloride?
Thaum koj tso aluminium hauv tooj liab chloride , cov tooj liab ua ke cov tshuaj chloride noj tam sim ntawd aluminium . Muaj qhov hnov ntxhiab tsw tsw thiab qee cov pa luam yeeb vim yog cov tshuaj lom neeg tshuaj tiv thaiv . Raws li cov tooj liab chlorides ua haujlwm tam sim ntawd aluminium , cov aluminium tig mus rau hauv ib qho xim av tsaus.
Qhov thib ob, cov tin puas cuam tshuam nrog tooj liab chloride? Tin reacts txawv nrog tooj liab (II) tshuaj chloride . Qhov txawv yog qhov ntawd tin (II) sulfate tsis tuaj yeem oxidized, thaum tin (II) tshuaj chloride tuaj yeem yog. Thaum xub thawj, lub tshuaj tiv thaiv Sn + CuCl2 => SnCl2 + Cu tshwm sim, thiab liab tooj liab nag xob nag cua.
Kuj kom paub, tooj liab chloride ua li cas nrog?
CuCl2 reacts nrog ob peb hlau los tsim tooj liab hlau los yog tooj liab (Kuv) tshuaj chloride nrog oxidation ntawm lwm yam hlau. Hloov ua lwm yam tooj liab (II) tshuaj chloride rau tooj liab (I) derivatives, nws ua tau yooj yim kom txo tau cov kua aqueous nrog sulfur dioxide raws li tus reductant: 2 CuCl2 +SO2 + 2 H2O → 2 CuCl + 2 HCl + H2SO.
Yuav ua li cas thaum Aluminium reacts nrog tooj liab sulphate?
Tooj Sulfate (CuSO4) tov yog xiav hauv xim. Thaum twg Aluminium yog ntxiv rau nws, A Displacement tshuaj tiv thaiv siv qhov chaw. Aluminium yog reactive ntau dua tooj liab yog li ntawd, Nws displaces Tooj los ntawm nws sulfate Kev daws nyob rau hauv thiaj li yuav tsim Aluminium Sulfate . Cov Aluminium Sulphate daws li no tsim yog colouless.

Yuav ua li cas rau aluminium foil hauv tooj liab chloride?
Thaum koj muab aluminium rau hauv tooj liab chloride, cov tooj liab ua ke cov chloride noj tam sim ntawm txhuas. Muaj qhov hnov ntxhiab tsw tsw thiab qee cov pa luam yeeb vim yog cov tshuaj tiv thaiv tshuaj. Raws li cov tooj liab chlorides ua haujlwm ntawm cov txhuas, cov txhuas hloov mus rau xim av tsaus
Yuav ua li cas thaum tooj liab oxide reacts nrog sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Puas yog tooj liab reacts nrog sulfuric acid?
Tooj liab tsis hnov mob nrog dilute sulfuric acid vim nws qhov txo qis dua qhov muaj peev xwm ntawm hydrogen. Tooj liab tsis hloov hydrogen los ntawm cov tsis-oxidising acids xws li HCl los yog dilute H2SO4. Yog li, thaum tooj liab rhuab nrog conc. H2SO4, cov tshuaj tiv thaiv redox tshwm sim thiab cov kua qaub raug txo kom sulfur dioxide
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
Yuav ua li cas thaum tooj liab II chloride reacts nrog txhuas?
Thaum koj muab aluminium rau hauv tooj liab chloride, cov tooj liab ua ke cov chloride noj tam sim ntawm txhuas. Muaj qhov hnov ntxhiab tsw tsw thiab qee cov pa luam yeeb vim yog cov tshuaj tiv thaiv tshuaj. Raws li cov tooj liab chlorides ua haujlwm deb ntawm txhuas, cov txhuas tig mus rau hauv cov xim av tsaus
