Neutralisation

• What is an acid?

  Substance that produced H+ ions when dissolved in water
• What is an alkali?

  Substance that produces OH- ions when dissolved in water
• What is the range on the PH scale?

  0-14
• Ionic equation for Neutralisation

  OH-(aa) + H+(aq) ——-> H20

  (salt not included as it’s different each time)
• Word Equation of Neutralisation

  Acid+Alkali——->Salt+Water
• What is a strong acid?

  An acid that completely dissociates in water to produce hydrogen ions.
• What is a weak acid?

  An acid that only partially dissociates in water and has a low concentration of hydrogen ions.
• Examples of Strong Acids

  HCL and H2SO4
• Examples of Weak Acids

  Citric,ethanoic and carbonic
