Answer to Question #180687 in General Chemistry for Nonetheless

Question

Procedures:

1. On a glass of water add a small amount of alcohol, observe its solubility in water, this is your first set-up.

2. On another glass of water add 1/2 teaspoon of salt, observe its solubility in water, this is your second set-up.

3. Get your 1 ruler sized strip of paper, put a glue on the entire strip on one face then fold the paper. Let the paper stick to make it half in size. This is your set-up 3.

4. Get another 1 ruler sized strip of paper, do the same procedure in number 3 but on this one use a baby powder after putting a glue and observe if they will stick together. This is your set-up 4.

Guide Questions:

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

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

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
