The pH scale and neutralisation

• what do acids and alkalis produce in aqueous solutions?

  • acids - hydrogen ions
  • alkalis - hydroxide ions
• what are bases, acids and alkalis?

  • b - compounds that neutralise acids
  • acids - produce hydrogen ions in aqueous solutions
  • alkalis - soluble bases which produce hydroxide ions in aqueous solutions
• what is the pH scale and what does a pH of 7 show?

  • measure of acidity/alkalinity of a solution
  • neutral solution
• state the general equation for a neutralisation reaction in a short, ionic form

  H+ + OH- > H2O
