Summary[edit]
| Description |
English: Unlike graphite, the burning of wood in O2 is more intense. Also, if we compare how wood burns in an atmosphere of air and O2, it is clear that the intensity of the burning in O2 is greater. When wood burns, a large number of cellulosic materials that are part of its structure, burn and release various gaseous products. Some of them are "acidic" gases, i.e. gases that form acids with water. The acids are responsible for the neutralization of the phenolphthalein alkaline solution and its discoloration.
The experiment was performed by Prof. PhD Miha Bukleski. The planning of the experiment also included the Prof. Emeritus PhD Vladimir Petruševski, Prof. PhD Marina Stojanovska and the student Mihail Trajkov, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.
Македонски: За разлика од графитот, горењето на дрвцето во O2 е поинтензивно. Ако се споредува како гори дрвцето во атмосфера од воздух и од O2, јасно е дека интензитетот на горење во O2 е поголем. При горењето на дрвцето, горат голем број целулозни материјали кои даваат различни гасовити продукти. Дел од нив се „кисели“ гасови, односно гасови кои со вода образуваат киселини. Киселините се одговорни за неутрализација на базниот раствор од фенолфталеин и неговото обезбојување.
Експериментот е изведен од проф. Миха Буклески. Во планирањето на опитот исто така биле вклучени пензионираниот проф. д-р Владимир Петрушевски, проф. д-р Марија Стојановска и студентот Михаил Трајков, Институт за хемија, ПМФ, УКИМ, Скопје, Македонија. |
