Conclusion!!!
The main goal of the experiment was to determine the concentration of a base solution using a titration method to find the concentration of the acid first, and find the identity of the base as well. We found that the base solution has a concentration of 0.03 M. The identity of the base to be calcium hydroxide Ca(OH)2.
We chose to follow this procedure because the purpose of a titration is to determine the unknown concentration of a substance by comparing it to a known concentration. By measuring the volumes, we can calculate the concentration of the substance being analyzed. Therefore, we were able to find the concentration of the solution. We the identified the base solution as calcium hydroxide by doing and flame test.
While doing this experiment, the volume of the base solution used in two trials was measured, resulting in values of 7.89 mL, and 10.56mL. The average volume of the base used we calculated was 9.23 mL.
Using the known concentration of the base and the volume of the base solution used, the concentration of the base solution was determined to be 0.03 M.
This conclusion suggests that the titration method used to determine the concentration of the base solution was accurate and reliable.
Possible Non-human errors
- Burette readings could’ve possibly given off the wrong reading.
Solution:
– Ensure the burette is properly cleaned before the experiment and periodically checked for accuracy.
– Use a burette with a clear and accurate scale, making it easier to read and reduce parallax errors.
– Take multiple readings and average them to improve accuracy and makes up for any individual errors.
2. Contamination or impurities in the reagents or equipment can affect the accuracy of the experiment.
Solution:
– Handle the tools used properly to avoid contamination from outside sources
– Make sure that the equipment is thoroughly cleaned and rinsed to remove any residue from previous use.
– Ensure that the chemicals are pure to minimize the risk of impurities affecting the experiment’s results.
