SOLVED: 1) What is the pKa of acetic acid? Over what range of pH values would an acetic acid/acetate buffer be effective? 2) What is the pKa of H2PO4-? Over what range of pH values would a dihydrogen phosphate/hydrogen phosphate buffer be effective?

Suggest a suitable buffer range for each of the following substances: (a) Lactic acid (p Ka=3.86) and its sodium salt (b) Acetic acid (p Ka=4.76) and its sodium salt (c) TRIS(p Ka=8.3 ; see Table 2.8) in its protonated form and its free amine form (d) HEPES (p Ka=7.55 ; see Table 2.8) in its zwitterionic form and its anionic form | Numerade

Come along with me into the buffer!!! Going into my first campaign event in roughly four years, I didn’t know what to expect. I wasn’t sure which lenses I should have with me as I wouldn’t have all access. I settled on a bag with 2 @canonusa R3’s, 10-20mm F4, 28-70 F2, 85 F1.2, 135 F1.8 and 100-300 F2.8. The more primes I can use (and F2 zoom) the more my images will pop and be different than everyone else. In the video clip you can see I start off with the 300 2.8 and move through the zoom rang
