Why should a magnesium ribbon be cleaned

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. They are very reactive since they have just two electrons in their outer electron shell. This coating hinders the burning of the ribbon as this layer does not burn easily. To do so we have to clean the surface of the ribbon. Cleaning the surface of the magnesium ribbon will remove the oxide layer from the surface and thus it will allow the ribbon to burn effectively to get the desired result. The magnesium ribbon burns in air producing intense heat and producing bright white light. The oxygen from the air reacts with magnesium to form the magnesium oxide. Always remember that magnesium only reacts with oxygen in the air to form an oxide coating on its surface but it does not react with the atmospheric nitrogen at all.

A physical change occurs when there is no change in the composition of a substance and no change in the chemical nature of the substance. A chemical change is a change that causes a change in the chemical properties of matter, resulting in the formation of a new substance. As an example, consider the burning of oil or fuel. Heat is evolved or taken in, the formation of bubbles, gas, and fumes, as well as a change in the colour of the reactants, can take place when they form a product. To carry out the Burning of magnesium ribbon in air and classify it as physical and chemical changes.

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

Hi, it looks like you're using AdBlock :. Answer Magnesium is a highly reactive element When kept open in the air, it reacts with the atmospheric oxygen to form Magnesium Oxide MgO The MgO layer does not burn or slows down the burning process and thus should be removed So the Magnesium ribbon should be cleaned with a sandpaper before burning to prevent the impurities deposited on the Magnesium ribbon from interfering in the reaction When cleaned, only pure Magnesium is present and burns in air with a dazzling flame. Hence to understand the answer to this question, we must understand that magnesium is a reactive element. Similarly, seawater is the most found substance as it is also found in the underground brines. To do so we have to clean the surface of the ribbon. Join Teachoo Black.

Unfortunately, it is not possible to do this at this point in time, but as we progress with our research work, we are quite optimistic we will develop some techniques for this too.
