In sanitary cleanser the element is present as sodium hypo chlorite. Sodium dithionite is a combustible solid which slowly decomposes when in contact with water or water vapor, forming thiosulfates and bisulfites. People with heart and kidney disease are recommended a sodium poor diet. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. Sodium compounds serve many different industrial purposes, and may also end up in water from industries. The electrolysis of aqueous sodium chloride produces sodium hypochlorite, NaOCl, a compound of sodium, oxygen, and chlorine used in large quantities in household chlorine bleach. Sodium borohydride is an odorless white to gray-white microcrystalline powder that often forms lumps. Sodium and water, in absence of air or oxygen, react to produce hydrogen gas and sodium hydroxide. In lamppost lights a small portion of sodium is often present in the neon lights, causing them to use fewer electricity. If a phenolphthalein indicator has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts. Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air.

In what way and in what form does sodium react with water? Phenol (C 6 H 5 OH) has an enough acidity to react with aqueous sodium hydroxide (NaOH). Water undergoes reduction to form Hydrogen gas - oxidation number of Hydrogen changed from +1 to 0. Using sodium metal, beryllium, thorium, titanium and zirconium can be extracted. This reaction is highly exothermic evolving a lot of heat which is sufficient enough to melt sodium due to its low melting point. The LC50 value for gold fish is 157 mg/L. Chemistry teachers love to use the sodium-water reaction when they are teaching students about the periodic table. Magnesium has a very slight reaction with cold water, but burns in steam. Sodium Metabisulfite contains 65% of SO2 available. (H 2). the destabilization of the hydroxyl intermediates by the electron-rich hydrocarbon groups (of course absent in water) also slows the progress of the reaction to some degree. As was mentioned earlier, sodium stems from rocks and soils. The unbalanced equation below shows the reaction between sodium and water. Sodium also produces hydrogen when reacting with water but the reaction of potassium with water is much more violent.
