Q
Q: If 2 moles of NaCl are dissolved in 1 kg of water, what is the van 't Hoff factor (i)?
Solution:
NaCl dissociates into 2 ions (Na⁺ and Cl⁻), so the van 't Hoff factor (i) is 2.
Steps: 5
Show Steps
Step 1: Understand that NaCl is a salt that can dissolve in water.
Step 2: Know that when NaCl dissolves, it breaks apart into two different ions: sodium (Na⁺) and chloride (Cl⁻).
Step 3: Count the number of particles formed when 1 formula unit of NaCl dissolves. It forms 2 particles (1 Na⁺ and 1 Cl⁻).
Step 4: Recognize that the van 't Hoff factor (i) represents the number of particles produced from one formula unit of a solute in solution.
Step 5: Since NaCl produces 2 ions when it dissolves, the van 't Hoff factor (i) is 2.
