strong acids and weak acids

• Strong acids ionise completely, whereas weak acids only partially ionise.
• strong acids:

  • sulfuric acid
  • nitric acid
  • hydrochloric acid
•  The dissociation of weak acids is a reversible reaction, which means that the products can react together to reform the acid.
• For a weak acid, does the position of equilibrium lies to the left
• weak acids:

  • citric acid
  • carbonic acid
  • ethanoic acid
• carbonic acid:

  • It does not fully ionise to release hydrogen ions
  • It will form a solution with a pH of less than 7
• strength of an acid:

  • The proportion of acid molecules which dissociate into hydrogen ions
•  an acids strength refers to how well it ionises (dissociates) when added to water
• a low pH mean a high concentration of H+ ions
• The dissociation of hydrogen ions from weak acids is a reversible reaction.

  This means as well as reactants forming products, the products can react to reform the reactants
