Given the following data, answer the question posed (5 points) phs Form K Н.G Hа" 7.41E-3 4.90E-5 4309 Which system (circle one answer) would make the best buffer to maintain pHH -3.8? (0) H,G alone (iv) HG/G (ii) HG alone (ii) G alone (iv) HG/HG

Please explain what the right answer is!

Answer 1

a form Ко eta o РК, H₂G 2013 HG 7041X10-3 4.90x10-5 - 4.31 for make best butter pka of acid should be 1 pka = pH 11 = 3.8 II. = 2.8 to 448 Since HE (pka = 4:31) comes in the butter range at given ph. Hence, Best butter would be os seuled HGT/G2-1 am Scanner
