Welcome to the blog guys in this article we are going to discuss about Why is sodium kept immersed in kerosene oil? Here you will get to know about definition of sodium. Please stay us with end do let us know in comment box which questions answer you are seeking. We will try to cover that too in our upcoming blogs. Why is sodium kept immersed in kerosene oil? Sodium, a highly reactive metal, is typically stored submerged in mineral oil (such as Also Read: Definition of Sodium Sodium is a chemical element with the symbol Na and atomic number 11. It is a highly reactive metal that is commonly found in nature in the form of various salts, such as sodium chloride (common table salt) and sodium bicarbonate (baking soda). Sodium plays a crucial role in the body, helping to regulate fluid balance, nerve and muscle function, and blood pressure. It is also used in a wide range of industrial and commercial applications, including food preservation and chemical manufacturing.

Hint: Sodium is an alkali metal and present in the first group of the periodic table. Its atomic number is 11. It can easily donate one electron to achieve a stable electronic configuration. HCl is a strong acid and reacts with metals but generally does not react with non - metals. Complete answer: i) Sodium $(N \uparrow $ Note: The reactive metals are the type of metals which could form reactions with acids, water or moisture, mineral acids and other potent acids. Reactive Metals like sodium, potassium, and lithium are highly flammable in nature. These reactive metals when in contact with air (presence of oxygen or moisture) catches fire and thus they are kept immersed in the kerosene oil to avoid injuries due to the accidental fire. The sodium metal is even not kept immersed in water because it reacts vigorously in the aqueous medium and forms sodium hydroxide with the liberation of hydrogen gas. The liberation of hydrogen gas (flammable), again can lead to accidental injuries due to severe ignitions.

Sodium is a very active metal that combines with oxygen at room temperature and burns with a brilliant golden-yellow flame. It reacts violently with water to produce hydrogen gas, which may be ignited by the heat of the reaction. So, it is kept in kerosene oil.

(a) Sodium is a very reactive metal so it reacts vigorously with the oxygen of air and catches fire. It is kept immersed in kerosene oil to protect it from the action of oxygen, moisture and carbon dioxide of air and to prevent accidental fires. (b) White phosphorus is kept immersed in water because it reacts spontaneously with oxygen of air to form phosphorus pentoxide but does not react with water. (c) No, because sodium reacts vigorously with water to form sodium hydroxide and hydrogen.
