Solubility hauv dej: Tsuas yog ruaj khov hauv kev daws
Tsis tas li ntawd, yuav ua li cas tshwm sim thaum carbonic acid reacts nrog limestone?
Teb. Limestone feem ntau yog tsim los ntawm cov ntxhia calcium carbonate (CaCO3). Los yog, yog tias muaj ntau dua kua qaub , ob hydrogen ions yuav teb nrog ib tug carbonate los tsim carbonic acid - H2CO3 - uas yuav decompose rau carbon dioxide - CO2 - uas nws thiaj li npuas tawm mus rau hauv huab cua, thiab dej H2O.
Tom qab ntawd, lo lus nug yog, carbonic acid puas tawg mus rau hauv? Raws li carbon dioxide nkag mus rau hauv cov ntshav, nws ua ke nrog dej rau daim ntawv carbonic acid , uas dissociates rau hauv hydrogen ions (H+thiab bicarbonate ions (HCO3-).
Ib yam li ntawd, nws raug nug, Acid Rain dissolve limestone li cas?
Los nag dej 'Ordinary' nag yog lawm acidic vim nws muaj yaj carbon dioxide uas tsim cov carbonic tsis muaj zog kua qaub . Thaum no qaug zog kua qaub tuaj rau hauv kev sib cuag nrog calcite, lub limestone pib rau yaj . Thaum ua ke, cov no tsim carbonic kua qaub (H2CO3). Qhov me ntsis kua qaub nag ces ntog rau hauv av.
Thaum limestone dissolves dab tsi tshwm sim rau cov khoom yaj?
Thaum acidic rainwater poob rau limestone los yog chalk, tshuaj tiv thaiv tshwm sim . Tshiab, soluble , tshuaj yog tsim nyob rau hauv cov tshuaj tiv thaiv. Cov no yaj nyob rau hauv dej, thiab ces raug ntxuav tawm, weathering lub pob zeb.

Puas yog ch3ch3 yog Lewis acid lossis base?
CH3CH3 tuaj yeem yog Lewis puag, thiab BBr3 tuaj yeem yog Bronsted-Lowry acid. CH3CH3 tuaj yeem yog Lewis puag, BBr3 tuaj yeem yog Bronsted-Lowry acid, thiab CH3Cl tuaj yeem yog Lewis puag
Puas yog pH 11 yog acid ib puag ncig lossis nruab nrab?
Lub pH ntawm 7 yog nruab nrab. pH tsawg dua 7 yog acidic. Ib qho pH ntau dua 7 yog qhov yooj yim. Qhov pH nplai yog logarithmic thiab vim li ntawd, txhua tus nqi pH qis dua 7 yog kaum npaug ntau acidic dua li tus nqi siab dua tom ntej
Puas muaj qhov sib txawv ntawm muriatic acid thiab hydrochloric acid?
Tsuas yog qhov sib txawv ntawm hydrochloricacid thiab muriatic acid yog purity-muriaticacid yog diluted rau qhov chaw ntawm 14.5 thiab 29 feem pua, thiab feem ntau muaj impurities xws li hlau. Cov impurities no yog dab tsi ua rau muriatic acid ntau daj-toned dua li purehydrochloric acid
Puas yog nitric acid yog carcinogen?
Nitric acid yog corrosive acid thiab muaj zog oxidizing tus neeg sawv cev. Concentrated nitric acid stains tib neeg cov tawv nqaij daj vim nws cov tshuaj tiv thaiv nrog keratin. Cov stains daj no tig txiv kab ntxwv thaum nruab nrab. Cov teebmeem hauv lub cev tsis zoo li, txawm li cas los xij, thiab cov tshuaj tsis suav tias yog carcinogen lossis mutagen
Puas yog acid rau dej lossis dej rau acid?
Thaum tshav kub kub tau tso tawm ntau heev uas cov tshuaj yuav ua rau kub hnyiab heev, txaws concentrated acid tawm ntawm lub thawv! Yog tias koj ntxiv cov kua qaub rau hauv dej, cov tshuaj uas cov ntaub ntawv yog diluted heev thiab qhov me me ntawm cov cua sov tso tawm tsis txaus rau vaporize thiab spatter nws. Yog li Ib txwm Ntxiv Acid rau dej, thiab tsis txhob thim rov qab
