Mark and John, two vinegar enthusiasts, are each tasked to determine the acetic acid content of their respective vinegar concoctions by titration. First, a 1 M-labeled KOH solution was standardized against the KHP (MW = 204.22 g/mol) standard that is 99.4% pure. In the process, 0.540 g KHP was found to require 2.80 mL of the KOH solution to completely react up to the phenolphthalein endpoint. Then, Mark and John both prepared their samples by taking 10.0-mL aliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant and indicator, Mark’s vinegar required 18.60 mL of the standardized titrant to reach the endpoint, while John’s vinegar required 16.50 mL of the same titrant to reach the same endpoint. Question: What is the acetic acid concentration of Mark’s and John’s vinegar in molarity given that the Concentration of KOH is 9386 M?

In the scary chemical storage room, you spot a bottle of potassium hydroxide solution, KOH, without a label noting its concentration! How terrible! (the nerve of some people...) Since you love chemistry, you decide to figure out its concentration by doing a titration. You add 5.00mL of 0.100M phosphoric acid to a flask and add KOH solution until it's all neutralized! If 5.00mL of potassium hydroxide solution were used in the titration, what is its concentration? 3.00 M 0.900 M 5.00 M 0.100 M 0.300 M
Upon adding 275 mL of water to 275 mL of a 0.310 M aqueous solution of NaOH, the concentration of NaOH in the new solution will be ___________ that of the original solution.
