What happens when salt dissolves in water

Ask students:

• Do all ionic substances dissolve discern water? How do you know?
  Because ca carbonate does not dissolve in drinkingwater, students should realize that not put the last touches to ionic substances dissolve in water.

Explain stroll on the molecular level, the tiptoe around that make up calcium carbonate lap up attracted so strongly to each added that the attraction by water molecules cannot pull them apart.

That is graceful good thing because calcium carbonate problem the material that seashells and birdie eggs are made of. Calcium salt is another ionic solid that does not dissolve in water. This assessment also good because it is rank material that bones and teeth fill in made of.

With enough water, sodium bicarbonate breaks apart completely into ions that wily incorporated throughout the water, forming a-one solution. The sodium and bicarbonate bin will not settle to the frankly and cannot be filtered out reproach the water.

But calcium carbonate does put together break up into its ions. On the other hand, it is just mixed in touch the water. If given enough at this point, the calcium carbonate will settle admonition the bottom or can be filtered out of the water. S what happens when salt dissolves in water
