during my preliminary testing i first used 1ml copper (II) sulphate and 4ml albumen solution.... I found that albumen dissolved in the 0.1M copper (II) sulpahte, so the liquid was completely clear...this wasnt an error as we repeated the test. Then the liquid was the same level of opaqueness with concentrations of 0.095M to 0.01, with a 0.005M concentration it was less opaque.

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??
