Carrying Out a Titration

• Acids and alkalis react together to forma a neutral solution (e.g. water)
• Titration - an accurate technique used to find out how much of an acid is needed to neutralise an alkali
• • When neutralisation takes place : 
  • The hydrogen ions (H⁺) from the acid join together with the hydroxide ions (OH⁻) from the alkali 
  • This forms water (H₂O) , with a neutral pH
  • H⁺ (aq) + OH⁻ (aq) → H₂O (l)

  
• You must use a suitable indicator in titrations
• If you have a strong acid and alkali , you can use methyll orange or phenolphthalein
• Strong acids

  • Hydrochloric acid 
  • Nitric acid 
  • Sulfuric acid
• Strong alkalis

  • Aqueous potassium hydroxide 
  • Aqueous sodium hydroxide
