I need to make 1M acidified aluminium sulfate. Okay the 1M solution is not a problem, What I nedd to know is do I acidify it with sulfuric acid. If so is it concentrated and how much for a 500mL solution. Thanks in anticipation.

Re: Acidified Aluminium Sulfate
Off the hook. Just showed the teacher what 199.926g of aluminium sulfate looks like and thats the amount for a 300mL solution that she wanted and she realised this probably can't be done. I live to fight another day YIPPEE.

Re: Acidified Aluminium Sulfate
Reading this, a chord struck somewhere in my memory. 
Off to google to check up
Found what I was looking for.
You add aluminium sulfate to the soil around hydrangeas to make the soil acid and the flowers blue, therefore aluminium sulfate is already acidic.
I just tested my 0.1M stock solution and got a pH of 3.4
