Lesson 2: An Introduction to Inorganic ions

Inorganic ions are charged atoms that do not contain carbon – for example iron, hydrogen, sodium and phosphate

You should know the following inorganic ions, as well as their properties and roles in the body:

  • Hydrogen ions ([katex]H^+[/katex])
  • Iron ions ([katex]Fe^{2+}/Fe^{3+}[/katex])
  • Sodium ions ([katex]Na^+[/katex])
  • Phosphate ions ([katex]PO_4^{3-}[/katex])
  • Calcium ions ([katex]Ca^{2+}[/katex])

Some specifications don't contain calcium, but we'll touch on it anyway (because extra knowledge doesn't hurt).
