A biochemical reaction needs to be buffered around a pH of 5.6. You currently have the following in your lab: water, acetic acid, sulfuric acid, hydrochloric acid, oxalic acid, acetate, oxalate, sulfate, ammonium and ammonia. What is the appropriate ratio of base to acid for your selected buffer system that you will need to buffer your reaction at this pH exactly? Report your final answer to one decimal place
