* Sodium is more reactive than hydrogen: Sodium is higher on the reactivity series than hydrogen. This means sodium has a stronger tendency to lose electrons and form positive ions (Na+).
* Reaction with acids: Sodium reacts vigorously with acids, like hydrochloric acid (HCl), to produce hydrogen gas (H2) and a sodium salt.
* Example: 2Na(s) + 2HCl(aq) → 2NaCl(aq) + H2(g)
* Reaction with water: Sodium also reacts vigorously with water, displacing hydrogen and forming sodium hydroxide (NaOH) and hydrogen gas.
* Example: 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
Important Note: These reactions are highly exothermic and can be dangerous. They should only be performed in a controlled environment by experienced individuals.
