Na + HCI ->

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.
