Strong acids & Weak acids

• How does the pH differ between strong and weak acids

  Strong acid will have a lower pH as it will fully ionise and so release more H+ ions
• 3 strong acids

  Hydrochloric acid

  Nitric acids

  Sulfuric acid
• Weak acids

  Carboxylic acids
• Is ionisation of strong acids reversible

  No
• Is the ionisation of weak acids reversible

  Yes
• Why are strong acids more reactive than weak acids

  Greater concentration H+ ions
• Good indicator for titration

  Methyl Orange
• Each time the pH increases by 1 how much does the H+ concentration change by

  Each increase by 1 pH the concentration of H+ ions gets 10x lower

  For each decrease by 1 pH the concentration of H+ ions gets 10x higher
