Question

Show all work! 1. Write the balanced chemical equation that describes acetic acid being neutralized by sodium hydroxide. 2. Suppose 3.109 g of NaOH was weighed out, dissolved, quantitatively transferred to a 250.0 mL volumetric flask, made up to the mark, and mixed well. What is the molarity of NaOH? 3. Burets are used to determine the volume of titrant delivered. The top mark on a buret is 0.00 mL, while the bottom-most mark is 50.00 mL. A 10.00 mL sample of vinegar was titrated with the NaOH solution in question 2 above. The initial volume of NaOH(aq) titrant in the buret was 2.50 mL, and the final volume was 32.08 mL. Calculate: (a) Net volume of titrant delivered (mL): (b) Moles of NaOH delivered: (c) Moles of acetic acid reacted: (d) Grams of acetic acid: (e) Concentration of acetic acid in the 10.00 mL sample (% w/v):
