Summary
| Description |
Македонски: Експеримент кој ги демонстрира дехидратационите својства на концентрираната сулфурна киселина. При контакт на концентрирана сулфурна киселина со сахароза, доаѓа до постепено јагленисување (карбонификација) на сахарозата. Реакцијата е проследена со ослободување на гасовити продукти кои овозможуваат образување на сунѓереста маса од јаглерод, која се издигнува од чашата. Реакцијата, приближно може да се опише со равенката:
English: An experiment that demonstrates the dehydration properties of concentrated sulfuric acid. When concentrated sulfuric acid comes into contact with sucrose, slow carbonification of the sucrose takes place. The reaction is accompanied by evolving of gaseous products that contribute to the formation of the foamy carbon product that rises above the beaker. The reaction can be described by the equation:
العربية: تجربة توضح خصائص نزع الماء لحمض الكبريتيك المركز. عندما يتلامس حمض الكبريتيك المركز مع السكروز، يحدث تفحم بطيء للسكروز. تصاحب التفاعل انبعاثات غازية تساهم في تكوين منتج كربوني رغوي يرتفع فوق الكأس، خطط للتجربة ونفذت من قبل مارينا ستويانوسكا، ميها بوكليسكي وفلاديمير بيتروشيفسكي، قسم الكيمياء، كلية العلوم الطبيعية والرياضيات، جامعة القديسين كيرلس وميثوديوس، سكوبيه، مقدونيا. |
