How does water weaken salt crystals? What happens to NaCl (salt) in water? Why is it important to know the lattice enthalpy of different ice-melting salts? How can you explain the melting of ice is not a chemical reaction? Why can't benzene dissolve sodium chloride?
Why does salt crystallize? Why do extrusive rocks have small crystals? Why do crystalline solids have a sharp melting point? Why are crystalline solids brittle? Why can grinding a solid into a fine powder increase the rate of reaction?
If you live in a city that gets lots of snow and ice, then you're familiar with road salt. Your city and local government likely has several de-icing trucks that spread road salt on the highways, streets and sidewalks to melt the ice. But why does salt melt ice, exactly? Con...
All salt is good, as long as the salt crystals are fine enough and dissolve easily. A lot can be said for different types of salt, some contain additives, some have other minerals next to the sodium chloride (NaCl) considered beneficial for you (like Celtic sea salt which is also lower ...
Today I have a fun ice boat science activity to do with kids to help teach them this concept. This would be a great activity to add to any physical science lessons. It would also make a fun summer learning activity! See also:Sink or Float: Density of Salt Water ...
To vary your buoyancy experiment, add salt to the water. Make the water look milky with salt. Because you won't want to fill a wading pool with salt water, you'll want to do this on a small scale, like an ice cube in a glass. Due to salt's density, items float higher in the...
A lot of us at Zero like a mug of low-calorie bouillon at mealtimes to replace the ritual of food. We’ve also been known to chew on pink Himalayan salt crystals to give our teeth something to do. When You Shouldn’t Supplement with Sodium ...
This binding action prevents the ice crystals from growing larger. And this is what prevents Notothenioids from freezing. Now, at that time, the waters the Notothenioids inhabited were still not freezing cold, so the protein didn't really make a difference as far as the fish's survival....
Why do copper (II) sulfate crystals not conduct electricity? Why does displacing copper using zinc produce a black precipitate? Why are most solid ionic compounds electrically non-conductive, whereas aqueous solutions of ionic compounds are good conductors?
Why does salt cause ice to melt? Why do molecular substances have relatively low melting points? Why does I_2 have a higher boiling point than F_2? Why is it important to add heat slowly and steadily when the temperature gets close to the melting point?
