Acids tuaj yeem nruab nrab los ntawm cov hlau carbonate Lub hydrogen ions (H +) los ntawm cov kua qaub ua nrog cov carbonate ions (CO 3 2-) los tsim cov dej thiab cov pa roj carbon dioxideIb qho ntsev kuj tsim. Cov ntsev muaj npe zoo ib yam li yav dhau los, noj cov hlau lub npe los ntawm cov carbonate thiab qhov kawg ntawm hom kua qaub siv.
Puas yog cov tshuaj tiv thaiv ntawm cov kua qaub thiab cov carbonate neutralization?
Thaum cov kua qaub ua rau cov carbonates, xws li calcium carbonate (pom hauv chalk, limestone thiab marble), ntsev, dej thiab carbon dioxide raug tsim. … Tsuas yog ntxiv cov tshuaj sodium carbonate rau cov tshuaj thiab yog tias cov pa roj carbon dioxide raug muab tawm, cov tshuaj yog acidic.
Neutralization tshwm sim li cas?
Ib qho tshuaj tiv thaiv tshwm sim yog tias koj sib tov ua ke cov kua qaub thiab lub hauv paus Cov tshuaj tiv thaiv hu ua neutralization. Kev daws teeb meem nruab nrab yog tsim yog tias koj ntxiv cov kua qaub thiab lub hauv paus ua ke. Neutralization yog cov tshuaj tiv thaiv exothermic, yog li cov tshuaj tiv thaiv sib xyaw ua kom sov thaum cov tshuaj tiv thaiv.
Yuav ua li cas thaum koj neutralize ib qho acid?
Ib qho tshuaj tiv thaiv tsis zoo yog thaum an acid thiab lub hauv paus react tsim dej thiab ntsev thiab koom nrog kev sib xyaw ntawm H+ ions thiab OH- ions los tsim dej. Thaum cov tshuaj neutralized, nws txhais tau hais tias cov ntsev yog tsim los ntawm qhov sib npaug ntawm cov kua qaub thiab lub hauv paus. …
Puas yog calcium carbonate thiab hydrochloric acid ib qho tshuaj tiv thaiv neutralization?
Thaum hydrochloric acid los rau hauv kev sib cuag nrog calcium carbonate, cov tshuaj tiv thaiv hauv qab no tshwm sim: CaCO3 + 2HCl → CaCl + CO2 + H2O, uas muab cov kua qaub nruab nrab nrog rau kev tsim cov khoom lag luam..
