Van't Hoff factor

Isotonic mafita - musamman kungiyar na mafita, wanda aka halin da osmotic matsa lamba. Shi ne na irin wannan muhimmanci, wanda ake halin da ruwa a cikin jiki, kamar: jini jini, hawaye, Lymph, da sauransu. Duk wadannan da taya ne postoyannoem matsa lamba a yankin na 7.4 ATM. Saboda haka, idan allura a cikin jiki da za a gabatar, da osmotic matsa lamba na ruwa da zai karye, kamar yadda za a iya karya irin wannan daidaituwa.

Don shirya irin wannan bayani, za ka bukaci ka yi wasu lissafin. A mafi m hanya na dauke ne ba kawai da van't Hoff factor isotonic. Tare da shi, wanda zai iya lissafta isotonic bayani taro na diluted abu, wanda ba shine electrolyte. A osmotic matsa lamba, da adadin bayani, da kuma ta da zazzabi dogara ne musamman wanda ya bayyana Clapeyron lissafi. Ana amfani da tare da girmamawa ga tsarma mafita, kamar yadda bisa ga doka na van't Hoff, da abubuwa narkar da a cikin ruwa zai nuna hali a cikin wannan hanya a matsayin gas da kuma saboda da su yi amfani da duk abin da ake kira gas dokokin.

Van't Hoff factor - wannan shi ne kome, a matsayin siga, wanda characterizes hali na al'amarin, a wani bayani. Da yake jawabi na lamba m na Van't Hoff factor daidaita da rabo na lamba darajar Collegiate Properties mallaki by warware wannan dukiya nonelectrolyte, kuma wannan taro, yayin da duk sauran sigogi kasance canzawa.

A zahirin ma'anar isotonic coefficient ya bayyana daga definition of kowane siga Collegiate. Dukan su ne dogara a kan maida hankali da dũkiyõyinsu a cikin barbashi bayani. Nonelectrolytes ba zai shiga a cikin dissociation dauki, duk da haka, kowane guda kwayoyin da abu zai kasance da barbashi. Wutan, a kan aiwatar da solvation ne ko dai kaucewa ko partially rarrabu cikin ions, fiili da dama barbashi. Sai dai itace cewa colligative Properties zai dogara ne a kan yawan barbashi žunsa daban-daban, Ina nufin ions. Saboda haka, isotonic coefficient zai zama wata cakuda daban-daban mafita na kowane irin barbashi. Idan muka yi la'akari da bayani na Bleach, ana iya gani cewa shi kunshi nau'i uku na barbashi: cations na alli hypochlorite, kazalika da chloride - anions. Isotonic coefficient zai nuna cewa electrolyte bayani yana more barbashi fiye da a da ba-electrolyte bayani. Coefficient zai dogara ne a kan ko wani abu da aka raba cikin ions - ba fãce da dissociation dukiya.

Tun da karfi Wutan suna gaba daya fallasa dissociation tafiyar matakai, shi ne wajaba ya sa ran cewa Van't Hoff factor a cikin wannan yanayin ne daidai da adadin ions dauke a cikin kwayoyin. Duk da haka, a gaskiya, da coefficient darajar ne ko da yaushe kasa da darajar, lasafta ta yin amfani Eq. Wannan matsayi ne na rasa a shekarar 1923 da Debye da Hiickel. Sun tsara ka'idar karfi Wutan: da ions ba zai zama cikas ga matsawa, kamar yadda za su samar solvation harsashi. Haka kuma, suna har yanzu zai tafiyar da juna, manyan ƙarshe da samuwar irin wannan kungiya da za a koma a daya shugabanci da bayani. Wannan shi ne abin da ake kira ionic jam'iyya da ion nau'i-nau'i. All matakai za su faru a cikin bayani don haka kamar yadda yake da shi ya ƙunshi 'yan barbashi.

Hulda da ions farawa zuwa Wane matsayin da yawan zafin jiki za su tashi, kazalika da rage su maida hankali. All saboda gaskiyar cewa a wannan harka rage da yiwuwar samun saduwa da daban-daban barbashi a cikin bayani.
