Yuav Balance HCl + KOH = KCl + H2O (Hydrochloric acid + Potassium hydroxide)
Yog li ntawd, qhov tshuaj tiv thaiv ntawm hydrochloric acid thiab potassium hydroxide yog dab tsi?
Peb muaj lub hauv paus hu ua poov tshuaj hydroxide , reacting nrog ib kua qaub hu ua hydrochloric acid . Qhov no yog hu ua neutralization tshuaj tiv thaiv . Qhov sib npaug ntawm cov tshuaj tiv thaiv is: KOH(aq)+HCl(aq) →KCl(aq)+H2O(l) K O H(a q) + H C l(a q) → K C l(a q) + H 2 O (l).
Tsis tas li ntawd, dab tsi ntsev yog tsim los ntawm hydrochloric acid thiab potassium hydroxide? Hydrochloric acid reacts nrog sodium hydroxide los tsim sodium chloride (a ntsev ) thiab dej. Sodium chloride yog ua nce ntawm Na + cations los ntawm lub hauv paus (NaOH) thiab Cl- anions los ntawm lub kua qaub (HCl). Hydrogen bromide reacts nrog poov tshuaj hydroxide ua form poov tshuaj bromide (ib ntsev ) thiab dej.
Tom qab ntawd, lo lus sib npaug ntawm cov poov tshuaj thiab hydrochloric acid yog dab tsi?
Potassium hydroxide (KOH) reacts nrog hydrochloric acid ( HCl ) tsim khoom poov tshuaj chloride (KCl), ntsev thiab dej (H2O). Qhov no yog ib qho tshuaj tiv thaiv neutralization.
Koj ua li cas sib npaug hydrochloric acid?
Nyob rau hauv thiaj li yuav tshuav nyiaj li cas H2 + Cl2 → HCl Koj yuav tsum nco ntsoov suav tag nrho H thiab Cl atoms ntawm txhua sab ntawm cov tshuaj sib npaug. Thaum koj paub ntau npaum li cas ntawm txhua hom atom koj muaj koj tsuas tuaj yeem hloov cov coefficients (tus lej nyob rau hauv pem hauv ntej ntawm atoms lossis compounds) thiaj li tshuav nyiaj li cas qhov sib npaug.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Dab tsi yog lub npe ntsev tsim los ntawm neutralization ntawm hydrochloric acid thiab sodium hydroxide?
Kev piav qhia: Cov tshuaj tiv thaiv ntawm sodium hydroxide (NaOH) thiab hydrochloric acid (HCl) yog cov tshuaj tiv thaiv nruab nrab uas ua rau muaj ntsev, sodium chloride (NaCl), thiab dej (H2O). Nws yog ib qho tshuaj tiv thaiv exothermic
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
