WebClean the beaker thoroughly, half-fill again with purified water, and repeat steps two and three using a drop of liquid soap instead of detergent. Compare what happens to what happened in the previous experiment. Repeat steps three and four, only this time use hard water instead of purified water. WebTitle is below graph and describes the data clearly (1 mark) 8. Describe, in molecular terms, what happened to the salt (NaCl) when it was added to the water, noting what special property of water was at work. (2 marks) 9. Explain paper clips float on water (again, consider the properties of water and the molecular bonds at play) (1 mark) 10.

WebQuestion: Part 2 – A Floating Paperclip 1. Unbend one segment of a paper clip to make a paper clip holder. 2. Fill a clear plastic cup approximately 3/4 full with tap water. (You can use the same cup as above but make sure you clean it out and get rid of any detergent that remains.) Take a picture and put it in the data section. 3. WebThen lay the paper clip on top of it. In a minute or so, the paper towel will sink, leaving the paper clip floating on top of the water. Even though the paper clip is still denser than the water, the strong attraction between the water molecules on the surface forms a type of "skin" that supports the clip.
