Summary

[edit]
Description
English: Graphite is the stable allotropic modification of carbon. To enable its burning in an atmosphere of nitrogen(I) oxide, it is necessary to heat it to red hot. After the heated piece of graphite is placed into the chamber filled with N2O, it is observed that the graphite continues to glow, unlike the result in air. The reaction that takes place is relatively slow because it occurs only on the surface of the graphite. The products of the dominant reaction are:
N2O(g) + С(ѕ) = CO(g) + N2(g)

The carbon monoxide does not react with water and as a result, the pH of the solution does not change. That is the reason why there is no change in the color of the phenolphthalein solution.

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: Графитот е стабилната алотропска модификација на јаглеродот. За да се овозможи негово горење на атмосфера од азот(I) оксид, потребно е графитот, претходно, добро да се зажари. Откако зажареното парче графит ќе се внесе во комората со N2O, се забележува дека графитот останува зажарен, што не е случај доколку истава реакција се изведува во атмосфера од воздух. Продуктите на оваа реакција се:
N2O(g) + С(ѕ) = CO(g) + N2(g)

Образуваниот јаглерод моноксид не се раствора во вода и како резултат на тоа, не се менува рН вредноста на средината, па затоа и не се забележува промена на бојата на базниот раствор од фенолфталеин.

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.
