Hydrogen, H2
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
Sodium metal and water
Water and sodium metal are reactants to produce sodium hydroxide and hydrogen gas. H2O + Na ==> NaOH + H2 !! VERY dangerous !! Sodium Metal and Water
when sodium is dropped into water sodium hydroxide is produced leaving out hydrogen.
Sodium chloride is dissociated in water in Na+ and Cl-. Sodium is an alkali metal.
Sodium is an unstable element which reacts violently when in contact with water. Sodium added to water can result in explosions.
Sodium chloride is soluble in water but don't react with water.
It is a chemical change, as sodium cannot evaporate (or water go to water vapor) without added heat. The main gas produced in this highly exothermic chemical reaction is hydrogen, liberated from the water by the combination of a hydroxide radical (OH) with the sodium, yielding a sodium hydroxide (NaOH) solution. The heat released is typically sufficient to ignite and burn both the sodium and the released hydrogen. So pure sodium metal oddly appears to catch fire and burn when placed in water.
Hydrogen, H2
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
In both reactions hydrogen gas is released but heat evolved in the sodium reaction is bigger.
A solution of sodium thiosulfate is produced.
Sodium metal and water
No, sodium metal cannot become water. Sodium is a highly reactive metal, and when it comes into contact with water, it reacts violently and releases hydrogen gas. This reaction can be dangerous and should be avoided.
Sodium hydroxide and Hydrogen
You want something that reacts with water and is exothermic. An example would be an alkali metal (such as sodium), or perhaps oxygen salts that react with water
