When sodium hydroxide (NaOH) reacts with manganese(II) chloride (MnCl₂), a double displacement reaction occurs, leading to the formation of manganese(II) hydroxide (Mn(OH)₂) and sodium chloride (NaCl). The balanced chemical equation for the reaction is:
\[ \text{2 NaOH} + \text{MnCl}_2 \rightarrow \text{Mn(OH)}_2 + \text{2 NaCl} \]
In this reaction:
- Manganese(II) hydroxide (Mn(OH)₂) is typically a precipitate that can form as a result of the reaction, appearing as a pale pink solid.
- Sodium chloride (NaCl) remains dissolved in the solution as it is highly soluble in water.
This reaction is commonly used in laboratory settings to demonstrate the formation of metal hydroxides and precipitation reactions.
