Determine if the salt Pb(BrO)2 is acidic, basic or neutral. HINT: Pb2+ Ka = 3.0 × 10-8 HBrO Ka = 2.8 × 10-9 neutral basic acidic
JUST NEED PART C, A AND B ARE FOR REFERENCE A)Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.17 M in KH2PO4, what concentration of Na2HPO4 would you need? (pKa for H3PO4, H2PO4−, and HPO2−4 are 2.14, 6.86, and 12.40, respectively.) (answer 0.234) B)Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ([HPO42−]+[H2PO4−]) to equal...
