ACIDS AND BASES (ALKALIS)
s
  • When atoms or groups of atoms lose or gain Electrons, they form charged particles called ions - either positively or negatively charged

*ACIDS:
s
  • Acids are Proton donors as they will react to lose Electrons to form positive H+ ions
  • These H+ ions make the Aqueous Solution Acidic

s
*BASES (ALKALIS):
s
  • Bases (Alkalis) are Proton acceptors as react to gain Electrons to form negative OH- ions
  • These OH- ions make the Aqueous Solution Alkaline
