EDEXCEL IGCSE CHEMISTRY: DOUBLE SCIENCE 复习笔记:2.6.2 Acids, Bases & Protons

Acids, Bases & Protons

 

Proton transfer

  • The earlier definition of an acid and a base can be extended
  • In terms of proton transfer, we can further define each substance in how they interact with protons

 

Acids

  • Acids are proton donors as they ionize in solution producing protons, H+ ions
  • These H+ ions make the aqueous solution acidic

 

Bases (Alkalis)

  • Bases (alkalis) are proton acceptors as they ionize in solution producing OH- ions which can accept protons
  • These OH- ions make the aqueous solution alkaline
