Chemistry / Re: When salty water freezes, why is the ice not salty?

You say the salt is excluded during the freezing process. Where does it go? Is it at the bottom of the ice cube tray? Did it just disappear? Is it not in the ice cube anymore? What if you put the ice cube in glass and allowed it to melt and then tasted the water. Would it taste salty?

Was the question answered? I'm sorry but I still don't know why salty water when frozen doesn't taste salty. When the ice melts doesn't the salt go back into solution? In order to taste it the ice has to melt a little doesn't it?

Science Experiments / Why does a magnet dropped through a copper pipe move so slowly?

« on: 24/03/2019 02:32:31 »

When a powerful  rare earth magnet is dropped through a copper pipe it moves very slowly through it. Is it because the electric/magnetic field generated by the magnet in the copper pipe is in opposition to the magnetic field (like pole) or is it attraction (unlike pole) to the magnet? In other words is it attraction or repulsion that slows the magnet?
