8.2 Properties of acids and bases

Properties of acids and bases

Reactions of acids with metals, bases, and carbonates

• Most acids react with metals, metal oxides, hydroxides, hydrogencarbonates and carbonates
• All these reactions produce a salt which is a compound of anion and cation
• Standard enthalpy change of neutralization: the energy change associate with the formation of 1 mol of water from the reaction between a strong acid and a strong base under standard conditions
  • Negative value because neutralization is exothermic

• For acids and bases:
  • 
• For metals higher than hydrogen on activities series:
  • 
• For metal carbonates and hydrogencarbonates:
  •
