Summary
| Description |
Македонски: Експеримент во кој се прикажува горење на сулфур во атмосфера од кислород. Употребена е проточна комора за согорување, поврзана со микропромивалка (последнава содржи воден раствор од индикатор метил оранж). Продуктот е сулфур диоксид (SO2) со примеси од сулфур триоксид (SO3). „Чадот“ што излегува од микропромивалката е, всушност, магла од сулфурна киселина добиена при реакцијата што може да се прикаже со равенката:
Се работи за киселински оксиди, како што се гледа од промената на бојата на индикаторот. Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.English: An experiment showing burning of sulfur in oxygen. A flow-chamber joined to gas washing-bottle (filled with solution of methyl orange) is being used. The product is sulfur dioxide (SO2) with some traces of sulfur trioxide (SO3). The 'smoke' that exits the gas-washing bottle is, in fact, a sulfuric acid fog generated in a reaction represented by:
The oxides are acidic, as can be witnessed by the colour change of the indicator. Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Română: Experiment ce demonstrează arderea sulfului în oxigen. Se folosește o cameră de curgere legată la o sticlă de spălare gaze (plină cu soluție de metil orange) is being . Produsul este dioxid de sulf (SO2) cu urme de trioxid de sulf (SO3). „Fumul” care iese din sticla de spălare gaze este, de fapt, un abur de acid sulfuric generat prin reacția:
Oxizii sunt acizi, și pot fi observați prin schimbarea de culoare a indicatorului. Planificat și efectuat de Marina Stojanovska, Miha Bukleski și Vladimir Petruševski, Catedra de Chimie, FNSM, Universitatea Sfinții Chiril și Metodiu, Skopje, Macedonia.中文：硫在氧气中燃烧的实验。气球搭建在反应装置上，燃烧产生的气体经过装有甲基橙溶液的洗气瓶。产物是二氧化硫，含有痕量的三氧化硫。进入洗气瓶的“烟”发生了如下反应：
