Sodium hydroxide solution and hydrogen gas are produced from the reaction of water and sodium.
<h2>Reaction of sodium and water</h2>
We observe bubbles coming out of the water when the sodium reacts with the water because of the formation of hydrogen gas which is insoluble in water so it moves into the atmosphere.
<h3>Products of the reaction</h3>
Sodium metal reacts rapidly with water to form sodium hydroxide (NaOH) solution and hydrogen gas (H2). This chemical reaction is exothermic because huge amount of heat is release from the solution so we can conclude that sodium hydroxide solution and hydrogen gas are produced from the reaction of water and sodium.
