Answer to Question #297009 in General Chemistry for Syd Hernan

Question

a. Get your 1 ruler-sized strip of paper, put 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.

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

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

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

Answer 1

a) the forces of attraction in solid solute are weaker as compared to forces of attraction In liquid solvent because of the differences in intermolecular forces

b) the forces between the glue and paper exhibit adhesive forces and the forces between the baby powder and the paper are cohesive.
