Q
Q: If 1 mol of NaCl is dissolved in 1 kg of water, what is the expected van 't Hoff factor (i)?
Solution: NaCl dissociates into 2 ions (Na+ and Cl-), so the van 't Hoff factor i = 2.
Steps: 4
Step 1: Understand what NaCl is. NaCl is table salt, which is made up of sodium (Na+) and chloride (Cl-) ions.
Step 2: Know that when NaCl dissolves in water, it breaks apart into its ions. This means 1 molecule of NaCl produces 2 ions: one Na+ ion and one Cl- ion.
Step 3: The van 't Hoff factor (i) represents the number of particles that a solute breaks into when it dissolves in a solution.
Step 4: Since 1 mole of NaCl produces 2 moles of ions (Na+ and Cl-), the van 't Hoff factor i is equal to 2.
