Summary
| Description |
Македонски: Стаклен сад (тиквичка со тркалесто дно) содржи презаситен раствор од натриум ацетат. Овој раствор е нестабилен и има тенденција спонтано да кристализира. Кристализацијата, исто така, може да се предизвика многу едноставно. Во овој случај тоа е направено со внесување на кристал од натриум ацетат трихидрат во растворот со стаклена прачка. Внесениот кристал игра улога на зародиш од каде започнува кристализација и се шири низ целата колба.
NaCH3COO(aq) = NaCH3COO·3H2O(s) Опис на процесот на кристализација Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.English: A glass vessel (e.g. a round bottom flask) contains supersaturated solution of sodium acetate. This solution is unstable and tends to crystallize spontaneously. The crystallization can also be easily initiated. In this case, it is induced by placing a solid sodium acetate trihydrate crystal in the solution by a glass rod. The inserted crystal acts as a seed where the crystallization starts and spreads all over the flask.
NaCH3COO(aq) = NaCH3COO·3H2O(s) Description of the crystallization process Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia. |
