How would the calculated value of pKa of the unknown acid be affected (higher, lower, or no change) if the following errors occurred? Briefly explain why in each case. The pH meter was incorrectly calibrated to read lower than the actual pH. During the titration several drops of NaOH missed the reaction beaker and fell onto the bench top. In part B of the procedure the acid was dissolved in 75 mL of distilled water rather than the 50 mL called for in the procedure.

Match each circumstance to an outcome. (Two circumstances may have the same outcome.) The pH buffers used to calibrate the pH meter were each 0.5 pH units high (4.5 and 7.5 rather than 4.0 and 7.0 respectively). You decided to take the pH after each addition of 5.0 mL of NaOH rather than after every 0.5 mL during the neutralization of your acid sample. 1. pKa would be unchanged. 2. pka would be too high. You refilled your buret between titrations of your unknown acid. Instead of 3. pKa would be too low. using 0.1 M NaOH as you did for the first titration, you used 0.2 M NaOH. While using the Half Volume method, your solution was dark pink (you overshot the endpoint) and you added the unreacted acid to this solution.

An aliquot of 20 ml of skim milk was placed in an Erlenmeyer flask. To the flask was added 3 to 4 drops of phenolphthalein. The sample was titrated in triplicate using a previously standardized NaOH solution 0.101M. The volumes of NaOH spent in the three experiments to reach chemical equivalence were 3.6ml, 3.7ml and 3.5ml. 1) Express the acidity of milk in g/L of lactic acid. 2) Assuming that the only acid present in milk is lactic acid, would you expect the pH corresponding to the equivalence point was 7?.
