1. Define retention factor. Explain why it is or isn't an intrinsic property of a substance. 2. A scientist was separating inks using a mixture of acetone and water as the mobile phase. Her assistant forgot to take out the paper and the solvent went past the top of the stationary phase. How will this affect the retention factors of the ink components? Will they be underestimated or overestimated? Explain.
