question 1:
The first thing you will need to do is to prepare a ~0.1M solution of NaOH, which you will standardize. You will prepare 250-mL of this solution using a 30% by volume NaOH stock solution. How much NaOH will you need to prepare this solution? Report your answer to 3 significant digits with units of mL. This is the volume you will need to prepare the standard solution in lab.
question 2:
You calculate your 1/2 equivalence point to occur at 6.50-mL. You only collected data points at 6.00-mL and 8.00-mL. What is the pH at the 1/2 equivalence point?
Volume (mL) pH 6.00 3.61 8.00 3.76Explanation / Answer
The pH at half way equivalence point at 6.5 mL must be around 3.64. As at volume pH at 7.0 mL will be between 3.6 to 3.76, some what around 3.68.
