Answer to Question #301031 in General Chemistry for Mizz

Question

Answer the following question based on your observations.

1. How will you describe the solubility of pure liquid materials on your set up 1 as represented by water as solvent and alcohol as solute?

2. Is there a strong force of interaction between the pure liquids? Why?

3. When you add a small amount of solute into a solvent in your set-up 2, what happen?

4. Will it have the same result uf you are going to use greater amount of salt? why?

5. How will you describe the forces of attraction between solid solute and liquid solvent?

6. How will you differentiate the results of set- up 3 and set-up 4?

7. Is there a difference in forces of interaction?

Answer 1

1.) Pure liquid materials have a high solubility when dissolved in the right solvent. Like dissoves like. Based on the setup 1, it was observed that ethyl alcohol dissolved in the water which is the solvent. This implies that pure liquid material has a high solubility.

2.) Yes, there is a strong force of attraction between the pure liquids. This is because they are strongly bonded by dipole-dipole force. Pure liquids have strong intermolecular force

The solubility of a solute is the amount of solute that will dissolve in a given amount of solvent to produce a saturated solution. For example, at 0^oC, we can dissolve a maximum of 35.7 g of solid NaCl in 100 mL of water (a saturated solution).
