he following evidence was obtained from an experiment to determine the solubility of calcium chloride at room temperature.
experimental value – theoretical value / theoretical value x 100
If the value had been greater than the theoretical value, select from the following list all that could be potential sources of error.
Temperature was higher than expected.
Temperature was lower than expected.
Solution was not pure distilled water and calcium chloride. Not all the water was evaporated.
Less than of the solution was measured.
More than of the solution was measured.
