Having a hard time finding specific gravity and pH values for ferric
oxalate that I made from ferric hydrate "mud" It is an olive green
but more yellow when seen through an eye dropper and a 5% solution
has a pH of 2.3. Anyone know of charts of S.G. vs concentration and
expected pH values? Any way to determine if free oxalic acid is present?
Thanks,
Peter Friedrichsen
