Materials needed for this separation of mixtures experiment

  • Breadcrumbs
  • salt
  • 1 teaspoon
  • 1 cup water

Experience

  1. In the glass, add a teaspoon of crumbs and a salt.
  2. Shake everything with a teaspoon.
  3. Wait a few minutes and watch the water again. What is at the bottom of the glass?
  4. Now test the water, what taste?

The explanation
Crumbs went to the bottom of the glass and the water has a salty taste.
Stirred by the spoon, salt and bread crumbs mixed with water.
But not the same thing happened: the salt grains are broken into small pieces,
molecules are distributed between water molecules, it is said that the salt
dissolved in water. The breadcrumbs are broken into many pieces
large enough to be visible, which are denser (“heavier”)
the water and end up falling. It is said that collect in the bottom of the vessel,
crumbs settle.
Slowly pouring salt water into another cup and waiting for the
the two glasses of water to evaporate (in the sun for example), is obtained in a glass salt
and bread in the other (is it salty!). This is the way to recover a large portion
salt has been mixed with the crumbs.
