Solution. When chlorine is passed through cold and dilute caustic soda solution, a mixture of sodium hypochlorite and sodium chloride is formed.
When sodium is added to water, the sodium melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.
Its single outer electron makes the metal highly reactive and ready to combine with others at the first opportunity – such as the moment the metal hits water. According to the textbooks, these reactive electrons rip apart the surrounding water molecules to release hydrogen gas and heat.
Hence sodium is greater in size than lithium it reacts with water more vigorously than lithium because it is more electropositive metal because of low ionization enthalpy. Therefore we can say that sodium reacts with water more vigorously than lithium because it is more electropositive metal.
Metal oxides that are soluble in water dissolve in it to further form metal hydroxide. But all metals do not react with water. Metals like potassium and sodium react violently with cold water. In case of sodium and potassium, the reaction is so violent and exothermic that the evolved hydrogen immediately catches fire.
Sodium is one of the highly reactive alkali metals. In its pure form, the soft, shiny metal reacts in water to form sodium hydroxide and hydrogen gas. Oh, and lots of heat—enough that the hydrogen gas ignites. The mutual repulsion of those positive charges rips the metal apart, and it blasts outward in tiny needles.
Five of the most explosive non-nuclear chemicals ever made
It is significantly more reactive in air as a liquid than as a solid, and the liquid can ignite at about 125 °C (257 °F). In a comparatively dry atmosphere, sodium burns quietly, giving off a dense white caustic smoke, which can cause choking and coughing.
Reaction of magnesium with water Magnesium does not react with water to any significant extent. This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water.
Magnesium reacts with water to produce hydrogen and a lot of heat. Metallic magnesium reacts only slowly, but magnesium vapour, produced when Mg burns, reacts extremely quickly due to the high temperature and efficient mixing, and produces heat very rapidly. Hence the explosion when water is added to burning magnesium.
For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water.
Mineral water rich in magnesium may therefore help lower the risk of cardiovascular disease. A small-scale 2004 study involving 70 adults with borderline hypertension and low magnesium levels found that drinking 1 liter of mineral water per day decreased their blood pressure.
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.
Magnesium is well known for its safety concerns in the industry due to its combustive, reactive nature when produced or stored in certain forms. The metal is often associated with a high risk of fire and explosion. Nevertheless, foundries process thousands of tons of molten magnesium every day.
Flammability. Magnesium is highly flammable, especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Flame temperatures of magnesium and magnesium alloys can reach 3,100 °C (5,610 °F), although flame height above the burning metal is usually less than 300 mm (12 in).
