NH₄Cl + NaOH → NaCl + NH₄OH
In this reaction, ammonium chloride (NH₄Cl) and sodium hydroxide (NaOH) react to form sodium chloride (NaCl) and ammonium hydroxide (NH₄OH). The reaction is a double displacement reaction, where the positive ions (NH₄⁺ and Na⁺) and negative ions (Cl⁻ and OH⁻) exchange places to form new compounds.
