Hauv qhov piv txwv, ib qho molecule ntawm HCl tsim ib hydrogen ion. Muab cov kua qaub ntau ntau los ntawm tus naj npawb ntawm hydrogen ions tsim los suav cov concentration [H +]. Piv txwv li, yog hais tias lub concentration ntawm HCL Hauv cov tshuaj yog 0.02 molar, ces qhov concentration ntawm hydrogen ions yog 0.02 x 1 = 0.02 molar.

Tom qab ntawd, dab tsi yog H + ntawm HCl?

Ua cov kua qaub uas muaj zog, peb tuaj yeem xav tias HCl tag nrho dissociates (ionizes) hauv dej. Tsis tas li ntawd, txij li ib qho molecule ntawm HCl yields ib [ H+ ], qhov sib npaug yog sib npaug rau cov molecular mass. Yog li ntawd ib tug molar tov ntawm HCl (ib molecular mass ib liter), yields ib molar tov ntawm [ H+ ].

Ib tug kuj yuav nug, ua li cas koj xam H + los ntawm pH? Cov pH ntawm ib qho kev daws yog sib npaug rau lub hauv paus 10 logarithm ntawm lub H+ concentration, muab faib ua -1. Yog koj paub cov pH ntawm kev daws dej, koj tuaj yeem siv qhov no qauv rov qab mus nrhiav cov antilogarithm thiab xam tus H+ concentration nyob rau hauv qhov kev daws teeb meem. Cov kws tshawb fawb siv pH ntsuas seb cov dej acidic lossis cov dej yooj yim npaum li cas.

Hauv no, puas yog H + Tib yam li HCl?

Hydrochloric acid ( HCl ) faib ua Hydrogen Ions (H +) thiab Chloride Ions (Cl-). Ntxiv H+ txhais tau tias kua qaub (tsis muaj qhov sib npaug ntxiv).

Puas yog HCl muaj zog acid?

A muaj zog acid yog ib kua qaub uas yog kiag li ionized nyob rau hauv ib tug aqueous tov. Hydrogen chloride ( HCl ) ionizes tag nrho rau hauv hydrogen ions thiab chloride ions hauv dej. Ib qho tsis muaj zog kua qaub yog ib kua qaub uas ionizes tsuas yog me ntsis hauv cov tshuaj aqueous. Vim HCl yog a muaj zog acid , nws conjugate puag (Cl) yog qaug zog heev.
