Water: describe how its molecular structure is responsible for its ability to serve as a solvent for salts and other ionic or polar materials. Explain how you can be sure it isn't a straight molecule?

Question

Is it because hydrogens can come off a attach to other things?

I don't know why it is not a straight molecule.

Also can precipitate float or sink?

Can it sink because it is what falls out after a reaction occurs so it wouldn't have any buoyancy?

Answer 1

Water is a polar molecule. If it were a straight line molecule it would not be polar.

PPts may or may not sink. It depends upon so many things. density, hydrophyllic or not, particle size and packing, etc. For example, powdered sulfur will float but a chunk of solid sulfur will sink.
