Strong and Weak Acids

• aqueous solution means dissolved in water.
• When an Acid splits it has ionised. Allowing Hydrogen ions to be alone.

  
• Strong acids FULLY ionise (in water). Whereas Weak acids PARTIALLY ionise.

  
• A) Hydrochloric Acid

  
• A) Sulfuric

  
• A) Nitric Acid

  
• Weak acids have reversible reactions.
• In a reversible reaction there is equilbrium between products and reactants.
• A) Weak

  
• Stronger Acids have a lower pH
• Concentration measures how much acid is in a volume of water
• The more acid in a liquid, the more concentrated the acid is.
• The Strength of an acid is how well it ionises. The concentration of an acid is the volume of acid.
• A solution decreases from pH 6 to pH 5. 

  
  

  By what factor has the concentration of hydrogen ions increased?

  x10 as you go down it adds another 0
• Do metals react more violently with water or acid?


  Acid
• Metal + Acid -> Salt + Hydrogen
