titration and Ka-measuring pH lab

**please type and answer both questions, thanks

1. Why do you rinse the buret with the sodium hydroxide solution and not with distilled water? How would your titration results be affected if you rinsed with distilled water before filling your buret?

2. In one of the steps of the Procedure you were told to add enough water so that the end of the pH electrode will be covered, but that the actual volume was not important. Explain why the volume of water you add in this step is not important.

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
