Answer #1

For an acid-base titration, the aim is mainly to determine the number of moles of acid/base that is required to react with the corresponding other one. Herein, we are keen to determine the number of moles of acid only. Since the presence of water will not affect the number of moles of acid present (since no acidic components that canreact with the base are present in water), it will not change amount of base required for neutralization. Hence, presence of water willnot affect the concentration.

Part A. The mass of KHC8H4O4 is measured to the nearest milligram; however, the volume of water in which it is dissolved is neverof concern—water is even added to the wall of the Erlenmeyer flask during the titration. Explain why water added to the KHC8H4O4has no effect on the data, whereas water added to the NaOH solution may drastically affect the data. 5. Part B.2. The wall of the Erlenmeyer flask is occasionally rinsed with water from the wash bottle...

The following questions involve the reaction of sodium hydroxide and succinic acid. Succinic acid is diprotic: the acid (H2C4H4O4) reacts with two of its hydrogens to give C4H4O42-. The balanced "molecular" equation for the reaction has coefficients of 2 for NaOH and 1 for succinic acid: 2 NaOH (aq) + H2C4O4 (aq) --> Na2C4H4O4 (aq) + 2 H2O (l) A student weights 1.700 g of succinic acid and dissolves it in water in a 250.0 mL volumetric flask.

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!
