Titration of Hydrochloric Acid: 1) Use the buret that is located near the hydrochloric acid container to dispense 25.00 mL of hydrochloric acid solution into a clean dry 100 mL beaker. Record the molarity of this solution on your data sheet. 2) Check to make sure that the volume on your sodium hydroxide buret reads 0.00 mL. If it does not read 0.00 mL, adjust it...

A vinegar titration was completed using a pH meter as an indicator of the changing pH. A 25.00 mL sample of diluted vinegar (diluted by a factor of 5) was placed in a beaker and subsequently titrated with 0.1098 M NaOH. A derivative curve of the titration suggested that the equivalence point occurred at 40.90 mL. Calculate the mass percent of CH_3COOH. (The density of vinegar is 1.008 g/mL.) Moles of base at the equivalence point = Moles of acid...

Pre-Lab Questions 1. Calculate the theoretical equivalence point (the volume!) in terms of ml NaOH adde each of the titrations. Assume the concentration of acid is 0.81 M and the concentration of base is 0.51 M. 2. Which equation can be used to find the pH of a buffer? Calculate the pH of a buffer containing 0.20 M CH3COOH and 0.20 M CH3COONa. What is the pH after...

In the second image it states that after I
pass the equivalence point, I should add 2ml of aliquots of NaOH
until there's no PH change. How do I identify when the equivalence
point is?

Question 6 (1 point) In your pre-lab, you were asked to determine the concentration for a 25.00 mL sample of acetic acid, CH3COOH (K= 1.8 x 10-5) of unknown concentration. Suppose you now repeat that same titration, using another 25.00 mL sample of that same unknown acetic acid and the same concentration of NaOH as a titrant. However, before you start titrating, you add an additional 100 mL of water to the flask containing our sample of acid. Everything else...
