After the conference we each have some new assignments. Mine - to test the ionic attachment of Magnesium to NCP. It's simular to the last tasks, but a different method. Instead of adding Mg solutions of different concentrations to NCP, we are adding NCP to pre tested concentrations of Mg solutions, and testing the difference between the two. The goal is to get really careful and accurate data, so yesterday and today was spent working on the method. Yesterdays concentrations had a 6 sample standard divination of 1.4%, hopefully today's samples will be even less.
