Which reactants could be used safely to prepare potassium chloride?
Direct Answer
Option A: aqueous potassium hydroxide and dilute hydrochloric acid
Potassium chloride (KCl) is safely prepared through a neutralization reaction between aqueous potassium hydroxide (a strong base) and dilute hydrochloric acid (a strong acid). This method avoids the highly reactive and hazardous metallic potassium, ensuring a controlled and predictable synthesis, crucial for chemical safety.
