Given three acid-base indicatorsâ€”methyl orange (end point at pH 4), bromthymol blue (end point at pH 7), and phenolphthalein (end point at pH 9)â€”which would you select for the following acid-base titrations? (a) perchloric acid with an aqueous solution of ammonia (b) nitrous acid with lithium hydroxide (c) hydrobromic acid with strontium hydroxide (d) sodium fluoride with nitric acid
Fifty cm3 of 1.000 M nitrous acid is titrated with 0.850 M NaOH. What is the pH of the solution (a) before any NaOH is added? (b) at half-neutralization? (c) at the equivalence point?

(f) Use your data to construct a plot similar to that shown in Figure 14.10 (pH versus volume NaOH added).
For the titration of 50.0 mL of 0.100-M HCl with 0.100-M NaOH, calculate the pH when these volumes of NaOH have been added: (a) 10.0 mL (b) 25.00 mL (c) 45.0 mL (d) 50.5 mL
In the experiment, we used titration to determine the total acid content ofsamples, which we reported in terms of molarity. Reporting acidity through pHmeasurements is quite different, in that we can only measure the amount of theacid in its ionized form. You were tasked to investigate a clear aqueous solutionof an unknown monoprotic acid. You decided to use two methods togather data.Method 1 – TITRATION: A 10. mL aliquot of the sample was diluted with 25 mLdistilled water. Two drops of phenolphthalein were added and then it was titrated3.54 mL of 0.048 M standardized NaOH to the endpoint.Method 2 – pH STRIP: You took 1 mL of the sample and used a pH strip toestimate the pH, which turned out to be around 3.3. Another 1 mL of the samplewas diluted with 9 mL of water. The pH was taken again and is now around 3.8.a) Calculate the molarity of the acid using the titration data.b) If we assume that the titrated unknown is a strong acid, predict thepH of the sample.c) Using pH strip results,…
You are making a potassium phosphate buffer that has 50 mM total phosphate (weighed out as KH2PO4), 160 mM KCl, and 7 mM dithiothreitol. You need 377 mL of buffer, which will be titrated to pH 50. What volume of a 2 M KH2PO4 stock solution should you add to the flask before diluting it to the final volume for your buffer? Report the volume in mL to the nearest 0.1 mL.
Prepare another 5 cuvettes with different concentration of Pi using the stock 1mM Pi, 0.5mM PNPP solution (in water) and 0.2M Tris-HCl, pH=8.00. For this part, the concentration of PNPP will remain constant at 0.150mM. Fill the table below (before coming to lab) and use it to prepare your cuvettes. The completed table must be in your pre-lab. Your blank for each reaction is the PNPP mixed with Tris-HCL and Pi. Again, prepare one cuvette at the time to minimize exposure of the PNPP to the air. You can prepare your next cuvette while your previous one is being read. previous one is being read.

Noting that the ratio of weak conjugate base(the anion of the acid) to weak acid in a titration can be determined by the equation where 10(number) is the anitlog(base 10) of the number, for example, 10(5.1-4.74) = 2.29 This can also be reversed. Given the ratio, the pH can be found: log {ratio} = pH - 4.74 Suppose that the ratio is 0.866, determine the pH where this occurs.
