Question two
A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 ml solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O2. The initial concentration of both the acid and the base are 0.0100 mol/0.1000...

2. If you prepared a 0.15 M CH3CO2H - 0.15 M CH3CO,Na buffer, would you expect the resulting buffer capacity to be higher, lower, or the same as the buffer you prepared in Part II (0.25 M CH,CO2H-0.25 M CH3CO Na buffer) of this lab? Be specific and use your data, Part II: Dilute Buffer Volume of CH.CO.Il.ml Molarity of CH.CO. Hmolel Beaker #1 10.00 ml 50 M Beaker #2 10.00 ml 0.50 M 0 Moles...

Experiment 6: The Standardization of a Basic Solution and the Determination of the MM of an Acid
Experiment 6: The Standardization of a Basic Solution and the Determination of the MM of an Acid *Note: This experiment is relatively long unless you know precisely what to do. Read the experiment before coming to class and arrive on time. After reading through the experiment answer the following question: 1. 7.0 mL of 6.0 M NaOH are diluted with water to a volume of 400 mL. You are asked to find the molarity of the resulting solution. a. First find out how many...
