Potassium reaction with chlorine observations
WebThe reaction of sodium with chlorine can be written as: sodium + chlorine → sodium chloride 2Na(s) + Cl 2 (g) → 2NaCl(s) Potassium. Potassium reacts more violently with chlorine than sodium does, showing how reactivity increases down the group. The salt potassium chloride (KCl) is produced by this reaction. The reaction can be written as: Web18 Jan 2024 · Potassium forms ions with a positive charge. A compound is formed when potassium reacts with chlorine, which forms ions with a negative charge. This electron is transferred to a chlorine atom to form a chloride ion. In KCl, both ions have full outer energy levels (noble gas configuration).
