Cov tshuaj tiv thaiv ntawm Acids thiab Bases
Cov ntsev yog ib qho nruab nrab ionic compound. Wb saib li cas a neutralization cov tshuaj tiv thaiv ua ob qho tib si dej thiab ntsev, siv ua piv txwv tshuaj tiv thaiv nruab nrab ntawm kev daws ntawm hydrochloric acid thiab sodium hydroxide. Zuag qhia tag nrho kev sib npaug rau qhov no tshuaj tiv thaiv yog: NaOH + HCl → H2O thiab NaCl.
Kuj nug, qhov sib npaug rau neutralization yog dab tsi?
Cov kev sib npaug neutralization ntawm HCl + NaOH muab rau koj H2O + NaCl twb sib npaug vim tias muaj ob lub moles ntawm H ntawm ob sab, ib mole ntawm Cl ntawm ob sab, ib mole ntawm Na ntawm ob sab, thiab ib mole ntawm O ntawm ob sab.
Ib yam li ntawd, lo lus kab zauv twg sawv cev rau qhov kev tawm tsam nruab nrab? 1) puag + acid → ntsev + dej Qhov twg lo lus sib npaug sawv cev rau qhov kev tawm tsam neutralization ?
Yog li ntawd, dab tsi yog neutralization cov tshuaj tiv thaiv nrog piv txwv?
Cov tshuaj tiv thaiv neutralization yog thaum ib qho kua qaub thiab lub hauv paus react tsim dej thiab ntsev thiab koom nrog kev sib xyaw ntawm hydrogen ions thiab hydroxyl ions los tsim dej. Lub neutralization ntawm lub zog kua qaub thiab lub hauv paus muaj zog muaj pH sib npaug rau 7. Piv txwv - 1: Thaum Sodium hydroxide ntxiv rau hydrochloric kua qaub.
Cov piv txwv ntawm neutralization yog dab tsi?
Neutralization yog ib qho tshuaj tiv thaiv uas acid thiab base react tsim ntsev thiab dej. Hydrogen (H +) ions thiab hydroxide (OH- ions) reacts nrog ib leeg los tsim dej.
