I know that albulem is soluble in dilute salt solutions....but is 0.1M copper (II) sulphate dilute?? and if so why did the others not do the same???
Using 9ml copper (II) sulphate to 1ml albumen solution the results were much nicer...i.e. a clearer gradient of opacity.
I used just simple observations by the way.
So would it be best to use greater, lower or equal volumes of albumen and copper (II) sulphate solution??
