See Mr Kremer`s Science Site - it is an excellent resource.
He has created dot point summaries for nearly, but not all, of the syllabus key focus areas.
The summaries for Topic 5 - Pollution Management, are VERY useful.
Download them from Mr Kremer`s site!

The pH scale


Rainwater is normally slightly acidic
Acid rain has a pH of below 5.6 (numerous sources state this)

There is dry deposition (oxide particles, aerosols and gases - fall directly onto the ground) and wet deposition (acidic oxides dissolve in cloud droplets - rain, mist, snow, hail) of acids - from the sources to the receptors;
