When sodium reacts with water, it produces sodium hydroxide (NaOH) and hydrogen gas (H₂). The reaction can be represented by the following chemical equation:
\[ 2 \text{Na} + 2 \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2 \uparrow \]
In this reaction, sodium (Na) reacts with water (H₂O) to form solid sodium hydroxide, which is a strong base, and hydrogen gas, which is released as a gas.
When discussing rocks, the products of the interaction depend on the specific minerals present in the rocks and the type of chemical or physical weathering processes occurring. For example, when carbonic acid (formed from carbon dioxide and water) reacts with certain silicate minerals in rocks, it can lead to the formation of clay minerals, dissolved ions (like calcium, magnesium, and potassium), and sometimes bicarbonate ions.
