Respuesta :
I know this maybe late but
-measurement of volumes when making the serial dilutions
-approximating the pH based on matching colors between pH papers
-miscalculation of pH values using the reference tables
-not boiling the cabbage long enough or hot enough to make the indicator solution
Hope this helps anyone who still needs it :)
The statements that have been responsible for the source of error has been statement B, C, and D.
While performing the laboratory experiments, the care has to be taken to check the experimental conditions. The handling errors have been the human errors that result in the inappropriate result of the experiment.
The statement that can be the source of error has been:
- Measurement of volumes when making the serial dilutions:
This has been the correct step and results in an accurate concentration of the sample. This has not been the source of error.
- Approximating the pH based on matching colors between pH papers:
This has been the source of error, it has resulted in the solution results.
- Miscalculation of pH values using the reference tables:
This can be the source of error.
- Not boiling the cabbage long enough or hot enough to make the indicator solution:
This has been the incorrect procedure and resulted in the error.
- Using distilled water to make your dilutions instead of seawater:
This has been the correct procedure and reduced the error.
Thus, the statements that has been responsible for the source of error has been statement B, C, and D.
