You titrate 100.0mL of HCl with 3.4 x 10-2M NaOH. You start with
50.0mL NaOH in the buret. The equivalence point is reached when the
reading on the buret is 24.4mL. Please show all work with proper
sig figs and units throughout.
A. Draw a picture of the titration setup, labeling where the HCl
is, and where the NaOH is. Label the start and end volumes on the
buret in your picture. How much NaOH was added to the HCl
solution?
B. What are you trying to calculate in this titration?
C. Calculate the quantity you identified in Part B.
D. What was the pH of the HCl solution before it was titrated?

A weak acid, HA, is partially titrated using NaOH. You start with 50.0mL of a 0.100 M HA and add 30.0 mL of a 0.100 M NaOH, and measure the pH of the solution at 7.00. What is the pKA of Ha? What would be the pH of the titration at the equivalence point (when 50.0 mL of NaOH is added)? I got the correct answer for the pKa (6.82), but don't know how to approach the second part. The...

We’re going to titrate formic acid with the strong base, NaOH. There is initially 100. mL of 0.50 M formic acid and the concentration of NaOH is 1.0 M. What is the initial pH of the formic acid solution? 2) What is the percent ionization under initial conditions? 3) After the addition of 10 mL of NaOH, what is the pH? 4) After the addition of 25 mL of NaOH, what is the pH? Think about where in the titration...

In this experiment, you will titrate an unknown acid with a base. It will be important for you to understand certain things about this titration in order to identify successfully your unknown. For all of the following questions, assume you are titrating an unknown monoprotic acid, HA, with NaOH solution. 0.146 g of HA is added to a beaker and made into a solution with ~100 mL of distilled water. As the titration proceeds, you keep track of the pH...

deviation for all three trials.
Part B-Preparation and standardization of an HCl Solution 1. Before you can titrate your saturated Ca(oH)a solutions, you must prepare and standardize a dilute solution of Hcl. With a graduated cylinder measure at least 6 mL of the stock Hcl lution, transfer it to a 125 mL Erlenmeyer, and dilute to approximately 100 mL...
