Reaction with Acids:
* Mechanism: Lithium is a highly reactive alkali metal. When it comes into contact with an acid, it readily donates an electron to the hydrogen ions (H+) present in the acid. This results in the formation of lithium ions (Li+) and hydrogen gas (H2).
* Example:
* 2Li(s) + 2HCl(aq) → 2LiCl(aq) + H2(g)
* Reaction Characteristics: These reactions are exothermic, releasing heat and producing a vigorous evolution of hydrogen gas.
Reaction with Bases:
* Mechanism: While lithium is not as reactive with bases as it is with acids, it can still react. In this case, lithium reacts with the hydroxide ions (OH-) present in the base to form lithium hydroxide (LiOH) and hydrogen gas.
* Example:
* 2Li(s) + 2H2O(l) → 2LiOH(aq) + H2(g)
* Reaction Characteristics: The reaction is less vigorous than with acids, but still releases heat and produces hydrogen gas.
Important Notes:
* Safety: Reactions of lithium with acids and bases are highly exothermic and can be dangerous. Always handle lithium with care and in a well-ventilated area.
* Reaction Rate: The reactivity of lithium with acids and bases is affected by the concentration of the acid or base, the temperature, and the surface area of the lithium.
