Summary[edit]

Description
Македонски: Експеримент за демонстрација на директна синтеза на алуминиум јодид. Во хомогенизирана смеса од алуминиум во прав и јод се додаваат неколку капки вода. По извесно време (т.н. индукционен период) доаѓа до бурна реакција проследена со емисија на интензивни обоени пари. Виолетовите пари се од јодот што испарува заради покачената температура, а кафеавите се најверојатно чад од адукт на продуктот на реакцијата со јод. Во системот се одвива егзоенергетска реакција 2Al(s) + 3I2(s) = 2AlI3(s) одговорна за набљудуваниот феномен.
Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.
English: Experiment showing a direct synthesis of aluminum iodide. Few drops of water are added to a homogenised mixture of aluminum powder and powdered iodine. After short time (an induction period) a vigorous reaction occurs followed by emission of intense colored vapors. The purple vapours are due to evaporation of iodine as a consequence of increased temperature of the system, and the brown ones are probably due to smoke of an adduct of the reaction product with excess of iodine. The exoenergetic reaction 2Al(s) + 3I2(s) = 2AlI3(s) is at the origin of the phenomenon observed.
Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.
Български: Експеримент, представящ директна синтеза на алуминиев йодид. В хомогеннна смес на алуминий на прах и йод се добавят няколко капки вода. След известно време, т. нар. индукционен период, започва динамична реакция последвана с емисия цветни изпарения. Виолетовите пари са резултат от йода, който при покачване на температурата започва да се изпарява, а кафявите, най-вероятно, се дължат на дима от адукт на реакционния продукт с излишък от йод. Екзерогенната реакция 2Al(s) + 3I2(s) = 2AlI3(s) е в основата на това явление. Експериментът е замислен и извършен от Марина Стояновска, Миха Буклески и Владимир Петрушевски, Институт по химия на Природоматематическия факултет в Скопския университет "Св. св. Кирил и Методий", Република Македония.
