1. A weak acid, HA, has a pKa of 4.11. a) At pH 7.11, what will the ratio of conjugate base to acid be? (Henderson-Hasselbach equation: pH=pKa + log [A-]/[HA]) b) Based on answer to "a," is there more HA or A- at that pH? c) At pH 2.11, what will the ratio of conjugate base to acid be? d) Based on answer to "c," is there more HA or A- at that pH? e) At pH 4.11, what will the ratio of conjugate base to acid be? f) Fill in the blank: if pH is greater than the pKa of a weak acid, there w...

Chem and Physics section - correct answer What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? - correct answer Because AMC is attached to the peptide on the carboxyl side. This suggests that an amide linkage involving the N atom in AMC is used to covalently attach the fluorophore to the peptide *a peptide bond between amino acids= covalent bond between carboxyl group of 1 amino acid to amino group of other, releasing water What expression give...
