Thaum sib tov, ib tug neutralization tshuaj tiv thaiv tshwm sim nruab nrab ntawm sodium hydroxide thiab cov acetic acid hauv vinegar: NaOH (aq) + HC2H3O2 (aq) → NaC2H3O2 (aq) + H2O (l) The sodium hydroxide yuav maj mam ntxiv rau lub vinegar nyob rau hauv me me los ntawm ib tug burette.

Ntawm no, dab tsi yog cov tshuaj tiv thaiv ntawm acetic acid nrog sodium hydroxide?

Acetic acid , CH3COOH, yuav teb nrog sodium hydroxide , NaOH , tsim sodium acetate, CH3COONa, thiab dej.

Tsis tas li ntawd, dab tsi ntsev yog tsim nyob rau hauv cov tshuaj tiv thaiv ntawm acetic acid thiab calcium hydroxide? Thaum twg acetic acid yog reacted nrog calcium hydroxide thiab cov khoom yog distilled qhuav, lub compound tsim yog acetone.

Tom qab ntawd, ib tus tuaj yeem nug, dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm acetic acid thiab sodium hydroxide?

Ua ntej sau tus qauv tshuaj sib npaug ntawm acetic acid reacting nrog sodium hydroxide los ua dej thiab sodium acetate. Yuav tsum sau li CH₃COOH + NaOH > H₂0 + CH₃COONa. Qhov thib ob, luam cov kab zauv hauv qab no uas tau sau tseg, tshwj tsis yog sau tawm daim ntawv ionic ntawm txhua molecule ntawm sab laug tes ntawm kab zauv.

Puas yog acetic acid soluble hauv NaOH?

Hauv kev sim a) Solubility ntawm carboxylic kua qaub , qhov tshwm sim qhia tias glacial acetic acid yog insoluble hauv ether, tab sis soluble hauv dej (H O) thiab hauv sodium hydroxide ( NaOH ). Cov neeg uas muaj qhov hnyav dua molecular yog insoluble vim qhov loj dua hydrocarbon feem, uas yog hydrophobic.
