Raoult ta Law.

Raoult ta dokar da aka kafa da baya a 1887 da daya daga cikin shahararrun Faransa lissafin kimiyya. Sunansa ya shaida. Raoult da dokar ta dogara ne a kan wasu nasabar rage tururi matsa lamba na dilution na ba-Wutan. Comparative matsa lamba akan rage impregnated biyu identically da mole sulusi da murabba'i na diluted abu. Wannan dokar kawo Faransa masanin kimiyya karatu bambancin mafita taya (ba maras tabbas) da kuma abubuwa (daskararru).

Daga Raoult ta Dokar za a iya koya cewa wani karuwa a ruwan zafin jiki ko rage sanyinsu na diluted bayani a cikin wani rabo tare da matauni rabo undiluted abu jari da kuma amfani da su sami ta kwayoyin nauyi.

Manufa bayani ne ake kira don haka da cewa duk da halaye shige da dacewa da bukatun na dokar Raul. More m mafita za a iya daukan kawai waɗanda suka kasance a cikin wadanda ba na iyakacin duniya gas da kuma taya. Wannan shi ne, sun yi sama da kwayoyin ba ya canza ta da shugabanci a cikin data kasance lantarki filin. Saboda haka, da zafi na tonawa zai zama sifili. Sa'an nan da kaddarorin da mafita zai zama da sauki a samu, tun lokacin da ta zama dole a yi la'akari ne kawai da asali dukiya bangaren kuma proportionality, a cikin abin da hadawa auku haticheskim hanya.

Tare da wadannan mafita yin irin wannan lissafi shi ne kusan ba zai yiwu. Saboda samuwar mafita, yawanci haifar zafi, ko akasin halin da ake ciki na faruwa - wannan bayani garwaya da zafi a kanta.

Yana kira da exothermic tsari a cikin abin da zafin rana tsara ya auku, da kuma endothermic tsari - daya, inda shi ne tunawa.

Colligative Properties daga cikin bayani ne waɗanda cewa su ne yafi dogara a kan maida hankali da mafita, maimakon daga cikin halitta diluted halitta abu. Colligative mai girma ne matsa lamba, zazzabi da misãlin da bayani kanta da gwargwado matsa lamba na sauran ƙarfi vapors.

A farko dokar Raul hadawa da mayar da hankali da matsa lamba na tururi a kan wani bayani da abun da ke ciki. A definition wannan dokar da aka rubuta kamar haka: PI = Pio * Xi.

A gwargwado matsa lamba tururi tara a mafita na gyara ne kai tsaye na gwargwado ga da darajar mole kasarun adadi a cikin bayani. A proportionality coefficient ne daidaita da tururi matsa lamba sama da mayar da hankali insoluble bangaren.

Tun da total hada sakamakon mole kasarun adadi na duka aka gyara na mafita ne 1, sa'an nan ga binary bayani kunshi gyara irin yadda A da B, za mu iya kacokan sakamakon rabo kuma daidai da magana na farko Raoult da dokar ta: (P0A-PA) / P0A = XB.

Na biyu dokar Raul - wannan shi ne wani sakamako na farko dokar, mai suna bayan da masanin kimiyya daga Faransa. Wannan dokar yana aiki ne kawai domin wasu tsarma mafita.

Rage sanyinsu hankali diluted mafita daga wadanda ba maras tabbas al'amari a kai tsaye rabo da jari daga molal mafita, da kuma ba su da wani dogara a kan halitta abubuwa diluted: T0fr-Tfr = Tfr = Km.

Kara tafasar batu wasu diluted mafita daga wadanda ba maras tabbas abubuwa ba dangane da yanayin da diluted abu, kuma shi ne kai tsaye na gwargwado bangaren molal mafita: T0b-tarin fuka = tarin fuka = em .
