The mass of the crystals was 110.3987 grams while the control had a mass of 131.7599 grams.

Figure 5

The mass of the crystals was 127.3198 grams while the same control had a mass of 131.7599 grams. Fig. 4 shows the mass of the crystals in a table, while Fig. 5 shows that mass of the crystals represented in a bar chart.

3.3 Special observations

Figure 6

It was observed that the crystals grown with the presence of a magnetic field had a more organised structure, with many tiny long rods, while the crystals grown in the control were large and grew in a messy way. (Fig. 6, 7, 8, 9) There were more crystals grown without a magnetic field in the beaker that those with the magnetic field, however this could be because the crystals grown without the magnetic field were larger. It was also observed that the crystals grown in the control had a higher opacity than the crystals grown above the magnet and were slightly translucent, while those that grew with the presence of a magnetic field were transparent.
