The median of a set of data is 24 and the mean is 30. Determine the type of skewedness

Question

shown by the data.
1. Calculate the pH of the NaOH solution.
2. Give a reason why the titration is repeated more than once.
3. The balanced reaction for the above titration is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2
O(l)
Calculate the concentration of the HCl

Answer 1

Without additional information about the data set, it is not possible to determine the type of skewedness shown by the data.

1. The pH of the NaOH solution cannot be determined without additional information such as the concentration of NaOH or the molarity of the solution.

2. The titration is repeated more than once to ensure accuracy and precision in the results. By repeating the titration, any errors or discrepancies in measurements can be identified and corrected.

3. The balanced reaction for the above titration is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

4. The concentration of HCl cannot be determined without additional information such as the volume and concentration of NaOH solution used in the titration, along with the volume of HCl required to reach the endpoint.
