Prac Results... Are they wrong?
« on: June 26, 2007, 07:25:00 AM »
Recently I performed a prac which involved joining 2 reactants together to form a precipitate. (all reactants dissolved in water at the time)

Anyway from the solubility table i have NaOH + Ba(NO3)2    which
should not produce a precipitate yet the solution changed colour to white and had a white precipitate in it.

My question is

is this possible under certain conditions eg different concentrations etc

or is it just a human error? eg wrong solution in the bottle?

Thanks in advance

Jacob

my bad

just realised my own stupidity

Ba(OH)2 has a 5.6g/100g of water solubility

therefore its prolly just we exceded this concentration...

thanks for any who looked in :P
