Zoo heev kub tau tso tawm tias cov tshuaj yuav ua rau kub hnyiab heev, txaws cov kua qaub tawm hauv lub thawv! Yog tias koj ntxiv cov kua qaub rau hauv dej, cov tshuaj uas cov ntaub ntawv yog dilute heev thiab qhov me me ntawm kub tso tawm tsis txaus rau vaporize thiab spatter nws. Yog li Ib txwm Ntxiv Acid rau dej, thiab tsis txhob thim rov qab.

Ua li no, koj puas ntxiv cov kua qaub rau hauv dej lossis dej rau cov kua qaub?

Ib txwm " Ntxiv tus Acid "Thaum koj sib tov kua qaub nrog dej , nws tseem ceeb heev rau ntxiv tus kua qaub mus rau dej ntau dua li lwm txoj hauv kev. Qhov no yog vim kua qaub thiab dej react nyob rau hauv ib tug vigorous exothermic cov tshuaj tiv thaiv, tso cua sov, tej zaum boiling cov kua.

Ib yam li ntawd, koj yuav ua li cas dilute acid nrog dej? Do cov tshuaj.

  1. Nco ntsoov ntxiv cov kua qaub rau hauv dej, tsis yog lwm txoj hauv kev.
  2. Thaum sib tov ob cov kua qaub, nco ntsoov ntxiv cov kua qaub uas muaj zog rau cov tsis muaj zog.
  3. Nws muaj peev xwm ntxiv ib nrab ntawm cov dej uas xav tau, diluting nws tag nrho, ces maj mam sib tov rau hauv cov dej ntxiv.

Tsis tas li ntawd, vim li cas cov kua qaub hauv dej?

Yog vim li cas koj ntxiv kua qaub rau dej yog tias koj ntxiv dej rau kua qaub , thawj poob ntawm dej reacts tam sim ntawd, thiab cov cua sov yuav siab txaus kom boil lub dej instantly, uas yuav tsuag kua qaub tawm ntawm lub thawv.

Yuav ua li cas thaum acid reacts nrog dej?

Muaj zog acids teb tag nrog dej tsim H 3O +(aq) (lub hydronium ion), whereas tsis muaj zog kua qaub dissociate tsuas yog ib feem ntawm dej . Conversely, muaj zog bases teb tag nrog dej los tsim cov hydroxide ion, whereas tsis muaj zog hauv paus teb tsuas yog ib feem nrog dej tsim hydroxide ions.
