-
As the pH decreases, the hydrogen ion concentration of the solution increases by a factor of 10
-
Carbonates and acids
As well as salt and water, carbon dioxide is also produced
Nanoparticles

-
-
Nanoparticles don't have the same properties as when they're in bulk due to large surface area to volume ratio. You only need small quantities to get the effect you want
Uses of nanoparticles; Medicine, electronics and cosmetics

Structure
ionic compounds
-
-
When melted or dissolved in water, ionic compounds conduct electricity because the ions are free to move
-
Polymers have very large molecules, the intermolecular forces between polymer molecules are relatively strong
