Answer:
Na+H2O------->NaOH+H2
Explanation:
Hope this helps you
Elementary sodium reacts strongly with water, according to the following reaction mechanism:
2Na(s) + 2H2O → 2NaOH(aq) + H2(g)
A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is heated and may ignite and burn with a characteristic orange flame. Hydrogen gas released during the burning process reacts strongly with oxygen in the air.
A number of sodium compounds do not react as strongly with water, but are strongly water soluble.
Solubility of sodium and sodium compounds
A number of examples of water solubility of sodium are available. De most familiar sodium compounds is sodium chloride (NaCl), otherwise known as kitchen salt. At 20oC solubility is 359 g/L, in other words adequately water soluble. Solubility is nearly temperature independent. Sodium carbonate (Na2CO3) is also adequately water soluble. Solubility is 220 g/L at 20oC.
Why is sodium present in water?
Sodium compounds naturally end up in water. As was mentioned earlier, sodium stems from rocks and soils. Not only seas, but also rivers and lakes contain significant amounts of sodium. Concentrations however are much lower, depending on geological conditions and wastewater contamination.
Sodium compounds serve many different industrial purposes, and may also end up in water from industries. They are applied in metallurgy, and as a cooling agent in nuclear reactors. Sodium nitrate is often applied as a synthetic fertilizer.
About 60% of sodium is utilized in chemical industries, where it is converted to chlorine gas, sodium hydroxide or sodium carbonate, and about 20% of sodium is utilized in food industries as a preservative or a flavouring agent. The remainder is applied for example as brine in winter.
Sodium hydroxide may be applied to prevent clogging of sewer pipes, and sodium carbonate is applied in water purification to neutralize acids. Sodium hydrogen carbonate is a constituent of backing powder, and is applied in textile and leather industries and in soap and cleanser production. In sanitary cleanser the element is present as sodium hypo chlorite.
