2B acids + bases

• Acid definition

  A proton donator; when dissolved in water, releases H+ ions
• alkali definition

  Bases that dissolve in water, releasing OH- ions into the solution
• strong acids

  Completely dissociate in aqueous solution, releasing all of their H+ ions
• Weak acids

  Partially dissociate in aqueous solution
• Examples of bases

  Metal oxides, metal carbonates and NH3
• Concentrated

  Many particles per unit volume
• Dilute

  Few particles per unit volume
• Base definition

  Proton acceptor
• products from acid + metal hydroxide

  salt + water
• Products from acid + metal oxide

  Salt + water
• Products from acid + metal carbonate

  Salt + water + carbon dioxide
• Products from acid + metal

  Salt + hydrogen
• Products from acid + ammonia (NH3)
