Question: What is the van \'t Hoff factor (i) for NaCl in solution?

Options:

Correct Answer: 2

Solution:

The van \'t Hoff factor (i) for NaCl is 2 because it dissociates into two ions: Na+ and Cl-.

What is the van 't Hoff factor (i) for NaCl in solution?

Step 1: Understand that NaCl is a salt that dissolves in water.
Step 2: When NaCl dissolves, it breaks apart into two separate ions: one sodium ion (Na+) and one chloride ion (Cl-).
Step 3: Count the number of particles (ions) produced when NaCl dissolves. In this case, there are 2 particles: Na+ and Cl-.
Step 4: The van 't Hoff factor (i) is the number of particles produced in solution. Since NaCl produces 2 ions, i = 2.
