a 50 mM buffer of monosodium dihydrogen phosphate and disodium monohydrogen phosphate at pH 7. The relevant pKa is 6.8. You'll have to figure out the concentrations of all the ionic species before computing the ionic strength. -Solve the problem using the Henderson-Hasselbalch equation to find the concentrations, use the two equations with two unknowns to solve. HPO4 = 0.031M, and H2PO4=0.019M. Then do the ionic strength. It's supposed to be u=0.096M, but I don't understand how this works. I'm...
