The reaction between sodium (Na) and hydrochloric acid (HCl) is a classic example of an acid-metal reaction. The balanced chemical reaction can be written as follows:
\[ \text{Na} + \text{HCl} \rightarrow \text{NaCl} + \frac{1}{2} \text{H}_2 \]
In this reaction, sodium (Na) reacts with hydrochloric acid (HCl) to produce sodium chloride (NaCl), which is common table salt, and hydrogen gas (H₂).
Key Points:
- Sodium is a highly reactive alkali metal.
- The reaction is exothermic and releases hydrogen gas, which can be observed as bubbles.
- The resulting sodium chloride (NaCl) is soluble in water.
This type of reaction is important in understanding how metals react with acids and the production of salts.
