    • Hydrogen Ions H+ which determine the pH of substances such as blood - the higher the concentration of hydrogen ions the lower the pH.
    • Iron ions Fe2+ are a component of haemoglobin which is an oxygen carrying molecule in red blood cells.
    • Sodium ions Na+ are involved in co-transport of glucose and amino acids.
