Tsis tas li ntawd, kev tshuaj xyuas ntawm 47 lwm cov kuab tshuaj qhia tau hais tias mole-fraction solubility ntawm O2 ib txwm tshaj li ntawm N2, nrog O2 / N2 solubility ratios xws li 1.20 hauv n-dodecane rau 2.31 hauv nitromethane.
Dab tsi yog qhov piv ntawm cov solubilities ntawm N2 thiab O2 hauv h2o ntawm 373 K muab KH N2)=12.6 104 atm thiab KH O2 7.01 104 ATM xav tias P N2 0.80 atm thiab P O2 0.20 atm?
Given that KH(N2 - 7.01 x 10 atm. Assume that po P(O2)0.2 atm 12.6 x 104 atm and KH (O2) PN2)0.8 atm and) [Ans. 2.22
Yuav ua li cas yog qhov piv ntawm solubilities?
Tus nqi ib txwm coj los rau qhov sib piv yog 1 feem ntawm cov kuab tshuaj rau 25 feem ntawm cov kuab tshuaj. Yog tias qhov piv txwv no dhau lawm (piv txwv li 1: 30) lub compound yog tsim los ua insoluble; yog tias nws qis dua tus nqi no (piv txwv li 1: 20) cov khoom raug suav tias yog soluble. Cov xwm txheej ciam teb tau muab tso rau hauv ob chav kawm thiab sim rau hauv txhua qhov.
Puas yog N2 lossis O2 cov kuab tshuaj?
Cua yog tsim los ntawm 80% Nitrogen thiab 20% Oxygencov kuab tshuaj hauv huab cua yog N2thiab cov kuab tshuaj yog O2.
Vim li cas O2 soluble hauv dej ntau dua N2?
Kev piav qhia: Qhov no yog vim cov roj molecules diffuse nruab nrab ntawm cov cua thiab dej saum npoo av. Raws li Henry Txoj Cai Lij Choj, cov ntsiab lus oxygen yaj ntawm dej yog proportional rau feem pua ntawm cov pa oxygen (ib nrab siab) nyob rau saum huab cua saum toj no 13. Nitrogen gas tsis hnov tsw nrog dej. Nwsyaj hauv dej.
