Will a paperclip rust in saltwater?

Answer 1

yes, because the salt makes the water heavier, so the water would be even more density, so the paper clip would be less dense than salt water
(I THINK) but it might not because of it's shape or texture

Answer 2

That, you'll really have to experiment.

Floatation works because of different densities of fluids. Dissolving salt into water makes the water more dense. However, at some point the water will no longer hold any more salt - pouring more will just cause it to sink to the bottom. This is when the liquid has become 'saturated.' At that point, the water will be as dense as it can be.

I do not now the exact answer to your question, and I doubt nobody will know until an experiment is conducted. If you do try, you will either get to see the paperclip float, or you'll be pouring salt in only to find it to sink to the bottom.

Answer 3

Yes, a paperclip will likely rust in saltwater because the salt content accelerates the oxidation process. The presence of moisture, oxygen, and ions from the saltwater will promote the formation of rust on the paperclip's metal surface.
