Sol se odmah otopila, te sam dodavao još soli sve dok na dnu nije ostalo nešto neotopljene soli. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019167 2020-01-13 20:42:11 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019167 SOL SE U VRUĆOJ VODI OTAPA, A MIJEŠANJEM SE TAJ POSTUPAK UBRZAVA (sol se brže topi). niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019394 2020-01-13 20:42:36 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019394 Dobivenu smjesu sam profiltrirao kroz papirnati ubrus, a staklenu čašu sam namazao kremom za ruke na bazi glicerina. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019588 2020-01-13 20:42:57 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431019588 OTOPINU SOLI JE POTREBNO PROFILTRIRATI DA SE VIŠAK NEOTOPLJENE SOLI UKLONI. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431020283 2020-01-13 20:44:24 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431020283 NA PAPIRNATOM UBRUSU ZAOSTAJE TALOG- NEOTOPLJENA SOL, A U FILTRATU ZAOSTAJE OTOPLJENA SOL - ČISTA OTOPINA. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431020836 2020-01-13 20:45:47 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431020836 UNUTRAŠNJOST STIJENKE ČAŠE TREBA NAMAZATI GLICERINOM DA SE SPRIJEČI RAST DRUGIH KRISTALA ODNOSNO DA SE SOL NE KRISTALIZIRA NA STIJENKAMA. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431021828 2020-01-13 20:48:07 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431021828 Nakon filtracije, konac zavezan na drveni štapić sam uronio do dna čaše i pustio da miruje tjedan dana. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431022760 2020-01-13 20:50:08 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431022760 U pokusu smo postupkom kristalizacije odvojili sastojke homogene smjese kuhinjske soli i vode. Tijekom nekoliko dana voda je polagano hlapjela, a kuhinjska sol se u obliku pravilnih tijela, kristala, hvatala na obješeni pamučni konac. Dobiveni kristali su čišći uzorci iste tvari nego što je ona bila prije otapanja. niko_sarlija https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431024238 2020-01-13 20:52:58 UTC https://padlet.com/niko_sarlija/rd0sqjrvgfs8/wish/431024238 1.
