Abstract(s)
To study the solubility of the copper sulphate in water, different
types of tablets were prepared from different polymers with different
percentages of CuSO4. The tablets were left in water for some days and
the amount of CuSO4 released from the tablets was determined by
measuring the absorbency of the final solution.
In the first phase of this work 10 samples were prepared,
corresponding to two similar sets. The results from these two sets were
not much different, and similar samples registered approximately the
same amount of CuSO4 in the water. By the seventh day more than the
maximum amount of CuSO4 expected was already registered in the
solution, meaning that all the copper sulphate present had been
transferred from the tablets to the water.
To try to get some more information about the influence of various
factors on the solubility of the CuSO4, another experiment was carried
out and more tablets of different sizes and from different polymers were
prepared.
From the results obtained it was possible to take some conclusions
regarding the way both factors, thickness and type of polymer, influence
the release of the copper sulphate from the tablets.
