SJG-2083CS online acid alkaline concentration Meter

Nyob rau hauv cov dej ntshiab, ib feem me me ntawm cov lwg me me poob ib hydrogen los ntawm H2O qauv, hauv cov txheej txheem hu ua kev sib cais. Cov dej yog li muaj qee tus me me ntawm hydrogen ions, h +, thiab residual hydroxyl ions, Oh-.

Muaj qhov sib npaug ntawm qhov sib npaug tas li thiab kev sib cais ntawm ib feem pua ​​ntawm cov dej lwg me me.

Hydrogen ions (Huag-) Hauv lwm cov dej lwg me me los tsim hydonium ions, h3o + uas feem ntau thiab tsuas yog hu ua hydrogen ions. Txij li cov hydroxyl thiab hydronium ions yog nyob rau hauv qhov sib npaug, kev daws yog tsis muaj kua qaub tsis alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline tsis alkaline los yog alkaline los

Ib qho kua qaub yog cov khoom siv hydrogen ions mus rau hauv kev daws, thaum lub hauv paus lossis alkali yog ib qho uas yuav siv hydrogen ions.

Txhua yam tshuaj uas muaj cov kua qaub tsis muaj cov tshuaj ntsuab yuav tsum muaj nyob rau hauv lub xeev uas tau yooj yim tso, tsis zoo li cov organic sib xyaw uas khi hydrogen rau cov roj ntsha atoms nruj me ntsis. Qhov PH yog li pab rau kev ntsuas lub zog ntawm cov kua qaub los ntawm kev qhia seb muaj pes tsawg hydrogen ions nws tshaj tawm kom daws.

Hydrochloric acid yog cov acid muaj zog vim tias cov ionic bond ntawm hydrogen thiab c clecoride hauv dej, tsim ntau cov tshuaj muaj zog acidic. Qhov no yog vim li cas nws muaj pH tsawg heev. Qhov kev sib cais no hauv cov dej kuj yog qhov zoo heev hauv cov nqe lus ntawm nquag nce, uas yog vim li cas nws tshwm sim yooj yim.

Cov kua qaub tsis muaj zog yog cov tebciab uas ua rau hydrogen tab sis tsis heev yooj yim, xws li qee cov organic acids. Acetic acid, pom nyob rau hauv vinegar, piv txwv li ntau hydrogen tab sis nyob rau hauv ib tug carboxylic acid koom nrog, uas tuav nws hauv kev sib txuas lus lossis tsis yog neeg sib khi.

Raws li qhov tshwm sim, tsuas yog ib qho ntawm hydrogens yog muaj peev xwm tawm ntawm cov molecule, thiab txawm tias, tsis muaj kev ruaj khov ntau tau los ntawm kev pub dawb.

Lub hauv paus lossis alkali lees txais hydrogen ions, thiab thaum ntxiv rau dej, nws sooaks ntawm cov dej uas muaj zog ntawm hydroxyl ion concentration, ua cov tshuaj alkaline lossis theem pib.

Ib qho piv txwv ntawm ib lub hauv paus ib txwm yog sodium hydroxide, lossis cov lus dag, siv hauv xab npum. Thaum cov kua qaub thiab cov alkali tau nyob rau hauv qhov sib npaug molour ntau, cov hydroce tshwm sim tau yooj yim, tsim cov dej thiab dej, ua cov tshuaj tiv thaiv hu ua nruab nrab.
