Why should a magnesium ribbon be cleaned

Questions from inside the book.

Hint: Magnesium is a very reactive metal. When it is kept in the open air it can react with the gases present in the air. Cleaning will remove those impurities formed due to the reaction with air. Complete Answer:. Let us see why it is important to clean the surface of the magnesium ribbon before burning it. Metals which are in the second group of the periodic table are called the alkaline earth metals.

Why should a magnesium ribbon be cleaned

Why should a magnesium ribbon be cleaned before burning it? Find the answer to this question and access a vast question bank customized for students. Ans : Magnesium is a very active compound chemically. Similarly, seawater is the most found substance as it is also found in the underground brines. Magnesium has the chemical formula Mg and is an important element of the periodic table. Hence a very famous question is asked regarding magnesium. Why is magnesium ribbon cleaned before burning? Hence to understand the answer to this question, we must understand that magnesium is a reactive element. Magnesium ribbon should be cleaned before burning it because it quickly forms the white layer of magnesium oxide, which does not burn. This happens when it burns in the presence of oxygen and moisture.

In association with Nuffield Foundation. Students weigh magnesium and heat it in a crucible, noting the change in weight they can discover the formula for magnesium oxide. This experiment is included in our Conservation of mass video, along with supporting resources , including illustrated technician notes , integrated instructions , worksheets, a structure strip and more. The practical activity takes around 30—45 minutes, depending on the competence of the class. Students should all be standing and should wear eye protection.

Why should a magnesium ribbon be cleaned

Magnesium is a highly reactive metal that readily reacts with oxygen in the air to form magnesium oxide. When a magnesium ribbon is burned in air, it undergoes a vigorous exothermic reaction, producing a bright white light and a white powdery residue. However, before burning, it is crucial to clean the magnesium ribbon to ensure a successful and efficient reaction. In this article, we will explore the reasons behind the necessity of cleaning magnesium ribbon before burning it in air. Magnesium is an alkaline earth metal with the atomic number 12 and a molar mass of It is known for its high reactivity, which is attributed to its low ionization energy and the presence of two valence electrons in its outermost shell.
