Given: pH: 7.60 Concentration (M): 0.050 mL: 100mL Determine the Mass of Each Component Recall that buffers are formed from conjugate acid/base pairs. Using the information given about your assigned buffer, determine how much of each component (acid and base) you will need in order to prepare it in the lab. (This will require a system of equations because there are two “unknowns.”) Note: the conjugate acid in this case is H2PO4−, and the conjugate base is HPO42−. 1. Using...
