What is formed when sodium absorbs moisture from air? give equation also |
|
Answer» When the sodium metal react with atmospheric oxygen to give sodium peroxide as a PRODUCT. By the stoichiometry we can say that 2 moles of sodium metal react with 1 mole of oxygen to give 1 mole of sodium peroxide as a product. Hence, the sodium peroxide is formed when sodium absorbs MOISTURE from air..EXPLANATION:When sodium is EXPOSED to moist air it forms a coatin of NaO2 and prevents the further reaction of the metal with air. With water it gives NaOH and H2. |
