APAKAH MAKSUD CRYOSCOPY dalam CORSICA?
Kemurungan mata beku
Kemurungan titik beku menerangkan proses di mana menambahkan larut kepada pelarut mengurangkan titik pembekuan pelarut. Contohnya termasuk garam dalam air, alkohol dalam air, atau pencampuran dua pepejal seperti kekotoran dalam dadah serbuk halus. Dalam kes sedemikian, sebatian tambahan adalah larut, dan pepejal asal boleh dianggap sebagai pelarut. Penyelesaian yang dihasilkan atau campuran pepejal pepejal mempunyai titik beku yang lebih rendah daripada pelarut atau pepejal yang tulen. Fenomena ini adalah apa yang menyebabkan air laut, (campuran garam (dan benda-benda lain) di dalam air) kekal cair pada suhu di bawah 0 ° C (32 ° F), titik beku air tulen.
Definisi cryoscopy dalam kamus Corsica
Takrif cryoscopy dalam kamus adalah penentuan titik pembekuan, esp untuk penentuan berat molekul dengan mengukur menurunkan titik pembekuan pelarut apabila jumlah larutan diketahui.
