Qhov sib txawv tseem ceeb ntawm acidity thiab alkalinity ntawm cov dej yog tias cov kua qaub ntawm cov dej yog cov dej muaj peev xwm los nruab nrab lub hauv paus whereas lub alkalinity ntawm dej txiav txim siab dej lub peev xwm los neutralize ib acid.
Peb tuaj yeem hu ua acidity ntawm dej raws li "lub hauv paus nruab nrab lub peev xwm" thiab alkalinity ntawm dej raws li "acid neutralizing peev". Peb tuaj yeem txiav txim siab ob qhov kev txwv no siv kev sim hauv chav kuaj. Nws muaj txiaj ntsig zoo hauv kev txiav txim siab cov dej zoo thiab qib dej paug.
Acidity dej yog dab tsi?
Acidity ntawm dej yog lub peev xwm ntawm cov dej kom tsis txhob muaj lub hauv paus. Peb tuaj yeem hu nws ua lub hauv paus neutralizing peev dej. Nws kuj tseem muab ntau npaum li cas ntawm tus qauv hauv paus uas peb yuav tsum tau ntxiv rau hauv dej txhawm rau txhawm rau nce pH ntawm cov dej mus rau ib qho nqi tshwj xeeb. Cov hom tshuaj tseem ceeb hauv dej yog hydroxide ions. Li no, lub sij hawm acidity kuj muab tau raws li cov dej lub peev xwm los neutralize hydroxide ions, tab sis nws tsis yog heev vim hais tias nws muaj peev xwm muaj lwm yam hom tshuaj lom neeg zoo li.
Cov kua qaub ntawm cov dej tshwm sim vim kev sib cais ntawm cov ntxhia acids xws li sulfuric acid thiab hydrochloric acid. Los yog lwm yam, cov kua qaub ntawm cov dej tuaj yeem yog qhov tshwm sim ntawm kev sib cais ntawm cov pa roj carbon dioxide. Hauv cov dej haus, carbon dioxide yog qhov tseem ceeb rau cov kua qaub ntawm cov dej. Yog hais tias dej muaj acidity siab, corrosiveness ntawm cov dej kuj yog siab. Yog li ntawd, nws tuaj yeem ua mob rau cov kav dej ua los ntawm tooj liab. Yog li ntawd, cov tooj liab thiab cov hlau lead ntau yuav muaj nyob hauv cov dej haus acidic.
Daim duab 01: Qhov kawg rau Titration ntawm cov qauv dej rau Acidity nyob rau hauv muaj Phenolphthalein
Feem ntau, peb tuaj yeem txiav txim siab cov kua qaub ntawm cov dej ntawm titration nrog sodium hydroxide rau txhua tus nqi pH. Phenolphthalein yog cov kua qaub-puag qhia tias peb siv nyob rau hauv no titration. Txij li qhov ntsuas no muab nws cov xim hloov ntawm pH 8.3, peb tuaj yeem titrate peb cov qauv dej rau tus nqi pH no. Txawm li cas los xij, ua ntej pib qhov kev sim, peb yuav tsum soj ntsuam cov xim ntawm qhov ntsuas ua ntej ntxiv cov sodium hydroxide vim tias peb cov qauv dej yuav muaj cov xim alkaline ntawm qhov ntsuas yog tias cov dej yog alkaline. Tom qab ntawd tsis muaj kev siv los txiav txim siab acidity ntawm cov dej vim acidity yog xoom.
Alkalinity dej yog dab tsi?
Alkalinity ntawm dej yog lub peev xwm ntawm cov dej kom tsis txhob muaj cov kua qaub. Qhov laj thawj tseem ceeb rau alkalinity ntawm dej yog ntsev ntawm cov kua qaub tsis muaj zog. Tsis tas li ntawd, cov hom tshuaj tseem ceeb uas ua rau alkalinity yog hydroxide thiab bicarbonate. Feem ntau, yog tias dej tsis huv, peb tuaj yeem soj ntsuam alkalinity es tsis yog acidity. Qhov no yog vim hais tias, tag nrho cov dej ntuj tau yaj carbon dioxide uas nws thiaj li tsim alkaline tshuaj hom xws li carbonate thiab bicarbonate. Li no, alkalinity ntawm dej yog qhov qhia tau zoo uas muab tag nrho cov pa roj carbon monoxide yaj hauv cov qauv dej.
Daim duab 02: Cov Hom Carbonate uas ua rau Alkalinity ntawm Dej
Dhau li ntawd, peb tuaj yeem txiav txim siab alkalinity ntawm cov dej los ntawm kev txiav txim siab npaum li cas acid peb yuav tsum tau ntxiv rau cov qauv dej txhawm rau txo cov pH ntawm cov dej mus rau ib qho nqi. Peb tuaj yeem ua qhov kev sim ntawm titration dej nrog cov kua qaub xws li hydrochloric acid.
Qhov txawv ntawm Acidity thiab Alkalinity ntawm Dej yog dab tsi?
pib nrog, qhov sib txawv ntawm cov kua qaub thiab alkalinity ntawm cov dej yog qhov Acidity ntawm cov dej yog lub peev xwm ntawm cov dej kom tsis txhob muaj lub hauv paus whereas alkalinity ntawm dej yog lub peev xwm ntawm cov dej kom neutralize cov kua qaub. Feem ntau ntawm cov sij hawm, cov dej tsis huv los yog cov dej ntuj qhia tau hais tias alkalinity es tsis yog acidity vim yog cov pa roj carbon dioxide yaj. Yog li ntawd, dej qias neeg muaj acidity siab.
Lwm qhov sib txawv tseem ceeb ntawm acidity thiab alkalinity ntawm dej yog tias cov neeg koom nrog acidity ntawm cov dej yog cov ntxhia acids xws li hydrochloric acid thiab sulfuric acid thaum rau alkalinity nws suav nrog yaj carbon dioxide, carbonate, bicarbonate thiab hydroxide ions.
Cov duab hauv qab no qhia qhov txawv ntawm acidity thiab alkalinity ntawm cov dej kom ntxaws ntxiv, thiab hauv daim ntawv teev npe.
Summary – Acidity vs Alkalinity of Water
Acidity thiab alkalinity ntawm dej yog qhov qhia tau zoo ntawm cov dej zoo vim tias feem ntau ntawm cov dej ntuj muaj alkalinity es tsis yog acidity. Tab sis, qhov sib txawv tseem ceeb ntawm acidity thiab alkalinity ntawm cov dej yog tias cov kua qaub ntawm cov dej yog cov dej muaj peev xwm los nruab nrab lub hauv paus whereas lub alkalinity ntawm dej txiav txim siab dej lub peev xwm los neutralize ib acid.
