Chlorine gas bleached daim ntawv litmus. Qhov no yog vim muaj cov hypochlorite ions. Yog li, thaum tshuaj chlorine (hauv txhua daim ntawv) yog ntxiv rau dej, tsis muaj zog kua qaub hu ua Hypochlorousacid yog tsim. Nws yog qhov no kua qaub , tsis yog tshuaj chlorine , uas muab dej nws muaj peev xwm oxidize thiab tua kab mob.
Hais txog qhov no, pH ntawm chlorine yog dab tsi?
Zoo tagnrho pH thiab Chlorine Cov kws tshaj lij theem Pas Dej feem ntau pom zoo nrog Lub Chaw Tiv Thaiv Kab Mob uas yog qhov zoo tagnrho pH rau lub pas dej da dej nyob nruab nrab ntawm 7.2 thiab 7.8. Txij li thaum pH 7 yog nruab nrab, qhov no txhais tau hais tias cov dej yuav tsum ib txwm me ntsis alkaline.
Tsis tas li ntawd, qhov pH thiab chlorine yuav tsum nyob hauv lub pas dej li cas? Yog tias pH yog siab dua 7, dej yog qhov yooj yim; yog itis hauv qab no 7 cov dej yog acid. Qhov zoo tshaj plaws pH rau pas dej ua ke dej yog 7.4, vim qhov no yog tib yam li cov pH nyob rau hauv tib neeg lub qhov muag thiab mucous daim nyias nyias. A pH ntawm 7.4 kuj muab qhov zoo tshuaj chlorine tshuaj tua kab mob.
Ib yam li ntawd, tib neeg nug, chlorine puas nce pH?
Chlorine gas yuav txo koj pH . Ob leeg ua kua tshuaj chlorine (sodium hypochlorite) thiab hmoov tshuaj chlorine (calcium hypochlorite) yuav tsa tus pH . Ua kua tshuaj chlorine yuav tsa tus pH ntau dua hmoov tshuaj chlorine . Txawm hais tias muriatic acid lossis sodiumbisulfate tuaj yeem siv los ua kom tsis muaj cov alkalinecompounds.
Dab tsi yog pH chlorine zoo tshaj?
Nyob rau hauv thiaj li yuav tshuaj chlorine ua siv tau , cov dej kho yuav tsum tau lim ua ntej kev kho mob kom txo tau cov khoom siv organic. Cov kev ua tau zoo ntawm tshuaj chlorine yog tswj los ntawm pH , kub, contacttime, thiab koob. Nruab nrab pH (6.5 mus rau 7.5) ua rau qhov siab tshaj plaws ntawm hypochlorous acid.

Puas yog ntsev daws acidic lossis yooj yim?
PH ntawm ntsev tov. Lub pH ntawm cov tshuaj ntsev yog txiav txim siab los ntawm tus txheeb ze lub zog ntawm nws ?conjugated acid-base khub. Cov ntsev tuaj yeem yog acidic, nruab nrab, lossis yooj yim. Cov ntsev uas tsim los ntawm cov kua qaub uas muaj zog thiab lub hauv paus tsis muaj zog yog cov ntsev ntsev, xws li ammonium chloride (NH4Cl)
Puas yog Ag + acidic lossis yooj yim?
Kauj Ruam 3: Nws txhais tau hais tias Ag + yog ua raws li lewis acid los ntawm kev txais ib khub ntawm electron los ntawm NH3 thiab NH3 yog ua raws li lub hauv paus los ntawm pub ib khub ntawm electrons
Puas yog American holly yooj yim lossis sib xyaw?
Nplooj yog tawv, evergreen, elliptic mus rau elliptic-ovate, 4-10 cm ntev, 2-5 cm dav, nrog ob peb mus rau ntau tus txha nraub qaum-tipped hniav, margins revolute. Paj tsis zoo, ntawm cov nroj tsuag cais, staminate paj nyob rau hauv axillary, pedunculate yooj yim los yog compound cymes; sepals 4, petals 4, dawb; stamens 4
Yuav ua li cas koj txiav txim siab yog hais tias ib yam khoom yog acidic los yog yooj yim?
Txhawm rau txiav txim siab seb cov khoom puas yog acid orabase, suav cov hydrogens ntawm txhua yam khoom ua ntej thiab tom qab cov tshuaj tiv thaiv. Yog hais tias tus naj npawb ntawm hydrogenshas txo cov tshuaj yog cov kua qaub (donates hydrogen ions). Yog tias tus naj npawb ntawm hydrogens tau nce ntxiv tias cov khoom yog lub hauv paus ( lees txais hydrogenions )
Puas yog cov lus ntsev acidic lossis yooj yim?
Properties of Table Salt: Rooj ntsev yog cov khoom tsim los ntawm neutralization ntawm cov kua qaub los ntawm lub hauv paus. Yog li nws tsis yog Acid lossis Base. Koj tuaj yeem siv pH Scale los qhia seb nws cov kua qaub lossis lub hauv paus
