Question

Sarah and Jim investigated the effect of temperature on the solubility of copper sulfate.
They dissolved copper sulfate crystals in the same volume of water until no more would dissolve. This means the solution was saturated.
They measured the mass of copper sulfate needed to make a saturated solution using water at different temperatures.
They plotted their results on a grid.
(a) One of the mass readings appears to be wrong (anomalous).
Name the anomalous result from the graph. (b) Suggest one mistake Sarah and Jim might have made to produce this anomalous
result.
