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.

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.

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. These properties make magnesium highly susceptible to oxidation, especially in the presence of oxygen.

Why should a magnesium ribbon be cleaned

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.

Old search 3. 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. Metals which are in the second group of the periodic table are called the alkaline earth metals. It's free :. Magnesium ribbon should be cleaned before burning it because it quickly forms the white layer of magnesium oxide, which does not burn. Maths Classes. This coating hinders the burning of the ribbon as this layer does not burn easily. If the magnesium oxide is not removed from the surface of the magnesium ribbon, in that case, the desired reaction might not be able to be obtained. Trending search 1.
