KHC8H4O4 (aq) + NaOH (aq) -> NaKC8H4O4 (aq) + H2O (l)
a. NaoH is approximately 0.1 M. Each titration will use 25.00 ml of KHP (potassium biphthalate). Suppose we want the endpoint of titration to occur at about 20ml of NaOH added. What should be the concentration of KHP?
b. You are going to prepare 250.0 ml of KHP to get enough solution to carry out up to 10 titrations. Using the concentration calculated above, describe how you will prepare this solution. Calculate the mass of KHP needed, and describe procedure and glassware you would use.
c. What is the maximum no of S.F possible in final result (concentration of NaOH)? Explain.
One of the treatments for gangrene and the bends, is hyperbaric oxygenation. This occurs in a chamber in which oxygen is used at higher-than-normal pressures.
What will be the resultant pressure when the stopcock is opened?

A reaction 3A2+ + 2B --> 3A + 2B3+ is used to make a battery. The standard Gibbs free energy change for the given reaction is -690 kJ. What is the standard potential (E ) for the battery.
Use the three-step method described in the module to predict the actual precipitates which form (if such is the case) when the following solutions are mixed
A container holds 355 mL of a mixture of nitrogen and carbon dioxide gases. Calculate the partial pressures of each gas if the container is at 27.3oC.
he initial rate of reaction of H2O2 -- H2O + 1/2O2 is found to be 1.7*10^-3 M S^-1. Assume that this rate holds for 2 minutes. Start with 165ml of 1.60M H2O2 at t=0. How many milliliters of O2 measured at 24C and 757mmHg
