Nov 08,2020 - Sodium is very reactive metals so that is stored in kerosene? Sodium is analkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged ion—the Na + cation. with oxygen and water. Sodium is a soft, silvery-white, highly reactive metal. If a sufficient quantity comes in contact with water, sodium can actually explode. - In food, water and other environmental media, sodium is in dissolved or combined form (salts) - Dissolved sodium is invisible, colorless, tasteless and odorless - Solid sodium salts vary in appearance, character and chemistry; ranging Sodium metal is one of the alkali metals which are soft and reactive and have relatively low melting points. How reactive is an atom of Sodium (Na) and why? YES. Question 1 options: Sodium (Na) is not very reactive because it does not have a full valence shell. Sodium reacts with water, acid and air, and does so spontaneously. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). When you will drop sodium in water...you can see flames on the surface!! Sodium metal is kept immersed in kerosene to prevent their reaction with oxygen, moisture and carbon dioxide of air. This makes Francium the most reactive, followed by cesium, rubidium, potassium, sodium and lithium. Sodium (Na) is not very reactive because it can only bond with Chlorine (Cl) to become salt. Sodium is the most common of them and it is a major component of table salt which is a compound with Chlorine. father17 father17 25.09.2019 Math Secondary School Sodium is a very reactive metal 2 0. Explain. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative. Sodium (or its alloys) may be used as reducing agents or catalysts, but they are not "essential" in making organic compounds. Answer: When metal M 3 is reacted with a salt of metal M 4 then it displaces metal M 4 from its salt solution and salt of metal M 3 is formed. What are the release dates for The Wonder Pets - 2006 Save the Ladybug? With water, the reaction with sodium is rapid and vigorous: #Na(s) + H_2O(l) rarr NaOH(aq) + 1/2H_2(g)uarr# All of this denotes considerable reactivity. Log in. Sodium is a soft, waxy, silvery reactive metal belonging to the alkali metals that is abundant in natural compounds (especially halite). Esters are made by reacting an alcohol with and acid in the presence of a strong acid; there is no sodium, metallic or as a compound, in esters, nor is it used in their production process.
