Ib qho tshuaj puag . Reacts nrog kua qaub kom tso tawm cov nplaim hluav taws kub thiab tshuaj lom gaseous hydrogen sulfide. Tsuav yog cov tshuaj khaws cia muaj zog alkaline, pH> 10, muaj tsawg heev tso H2S. Ntawm pH = 7, qhov feem pua ntawm H2S tso tawm yog ze rau 80%.

Ntxiv rau qhov no, yog sodium sulfide acidic lossis yooj yim?

Zoo li sodium hydroxide, sodium sulfide yog muaj zog alkaline thiab tuaj yeem ua rau tawv nqaij kub hnyiab. Cov kua qaub react nrog nws kom sai tsim hydrogen sulfide , uas yog tshuaj lom heev.

Ib yam li ntawd, sodium hydrosulfide siv rau dab tsi? Sodium hydrosulfide , paub los ntawm nws cov cim tshuaj NaHS (feem ntau hais tias "nash") yog siv hauv tawv tanning, pulp thiab ntawv, tshuaj, dyeing, thiab ntxhia extraction industries. NaHS yog siv li cov khoom ntshiab (flake) los yog ntau dua li cov tshuaj hauv dej.

Ua li no, NaHS puas yog kua qaub?

NaHS yog ib qho tseem ceeb reagent rau cov synthesis ntawm cov organic thiab inorganic sulfur tebchaw, qee zaum raws li cov khoom reagent, feem ntau yog cov tshuaj aqueous.

Sodium hydrosulfide.

Cov mis Na2S txhais li cas?

Sodium sulfide yog chemical compound nrog cov qauv Na2S, los yog ntau tshaj nws cov hydrate Na2S · 9 H2O. Ob leeg yog cov xim tsis muaj dej-soluble ntsev uas muab cov tshuaj alkaline zoo heev. Thaum raug huab cua ntub, Na2S thiab nws cov hydrates emit hydrogen sulfide, uas tsw zoo li qe rot.
