Answer 1

The correct answer is NaCl, CaCl2 and MgSO4.

Key Points

1-1 electrolytes: NaCl (Sodium Chloride) dissociates into one Na⁺ and one Cl^- ion in solution.
2-1 electrolytes: CaCl2 (Calcium Chloride) dissociates into one Ca²⁺ ion and two Cl^- ions in solution.
2-2 electrolytes: MgSO4 (Magnesium Sulfate) dissociates into one Mg²⁺ ion and one SO4^2- ion in solution.
Electrolytes are substances that produce ions when dissolved in water and conduct electricity.

Additional Information

Electrolyte Classification: Electrolytes are classified based on the number of ions they produce in solution. For instance, 1-1 electrolytes produce two ions, 2-1 electrolytes produce three ions, and 2-2 electrolytes produce four ions.
Conductivity: The ability of an electrolyte solution to conduct electricity depends on the concentration of ions. Higher ion concentration generally means higher conductivity.
Dissociation: The process by which an electrolyte dissolves in water and separates into ions is called dissociation.
Importance: Electrolytes are crucial for various physiological functions, including nerve transmission and muscle contraction, due to their ability to conduct electrical impulses.
Examples: Other examples of common electrolytes include KCl (Potassium Chloride), Na2SO4 (Sodium Sulfate), and BaCl2 (Barium Chloride).
