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.
