killing germs.
The aquarium filters, airstones running, jumping fish and other normal water movement cause salty water to be sprayed onto the lid. The water evaporates, leaving the salt behind.
I would assume some kind of polution and syphon off the bottom of the tank and do a massive water change.
Salt is hygroscopic, absorb water.
You place the salt / sand mixture in warm water. The salt will dissolve in the water and you than then four the salt solution off the sand, leaning just sand. Then boil the salt solution untill all the water evaporates, leaving the salt.
It's not the color that is significant, its the fresh water that the ice cubes were made with. Salt water is heavier than fresh water so the fresh water floats a top the salt water.
The water becomes murky and the salt rises to the top
Using a Dean stark collection arm with an attached condenser and boiling the water off. You could also use a distillation head with an angled condenser (angled down from the top of the salt water containing flask) and collection flask at the lower end of the condesner.
The body of water you will never sink in is The Dead Sea, because it has allot of salt and the salt will push you to the top of the water THEREFORE you WILL NOT sink.
Because the salt in the water builds up at the top. But in regular water, it has nothing in it to build up...
Fresh water is less dense than salt water because it has fewer dissolved ions. This difference in density causes fresh water to float on top of salt water, creating distinct layers. Salt water is more concentrated with ions, making it denser and causing it to sink below the less dense fresh water.
No, it will be at the bottom - difference in density.
Yes, because salt water is denser than fresh water, it will typically float on top of fresh water in a layered system called stratification. This is due to the differences in salinity and density between the two types of water.
