Possible sources of experimental error in this lab could include:
1. Measurement errors: Errors in reading or recording the measurements accurately could lead to experimental error. This can make the results larger or smaller, depending on whether the measurements were consistently overestimated or underestimated.
2. Environmental factors: Temperature, humidity, and other environmental conditions can affect the outcomes of the experiment. For example, if the temperature was higher than expected, it could cause the reaction to proceed faster and yield larger results. Conversely, if the temperature was lower than expected, it could slow down the reaction and yield smaller results.
3. Contamination: If the materials used in the experiment were contaminated, it could affect the chemical reaction and lead to incorrect results. This can make the results larger or smaller depending on the nature of the contamination and its impact on the reaction.
4. Procedural errors: Mistakes in following the experimental procedure could introduce errors. For instance, if a step was skipped or performed incorrectly, it could lead to inaccurate results. The direction of the error (larger or smaller) would depend on the specific mistake made.
5. Equipment errors: Malfunctioning or improperly calibrated equipment could also introduce error. If the equipment was not properly calibrated, it could lead to incorrect measurements and therefore affect the results. The direction of the error would depend on the nature of the equipment malfunction.
6. Human errors: Errors made by the experimenter, such as misreading the scale, improper timing, or incorrect mixing technique, could also contribute to experimental error. These errors can make the results larger or smaller, depending on the specific mistake made.
It is important to note that the actual impact of these sources of error on the results would depend on their magnitude and the specific experimental setup. Without additional information, it is not possible to accurately predict whether the errors would make the results larger or smaller.
