Abstract

Uređajem vlastite izrade mjerena je topljivost alkalijskih nitrata (NaNO₃/KNO₃/RbNO₃/CsNO₃) u smjesi otapala glicerol [HOCH₂CH(OH)CH₂OH] + H₂O u ovisnosti o masenom udjelu glicerola (0,0 – 1,0) pri 35 i 45 °C. Određene su gustoće i indeksi loma zasićenih otopina NaNO₃/KNO₃/ RbNO₃/CsNO₃ + smjesa otapala glicerol + H₂O. Eksperimentalni rezultati su pokazali da se s povećanjem masenog udjela glicerola u svim sustavima smanjuju topljivost soli i gustoća otopine, dok se indeks loma postupno povećava. Topljivost, indeks loma i gustoća bili su postavljeni po četveroparametarskoj empirijskoj jednadžbi.

Keywords
