Problem 2.20 -Enhanced - with Solution 59 of Correct At pH 7.06 H PO4] and[PO will be negligible. The pKa of H3 PO 2.14, which is five pH units below 7.06. Thus, the Henderson-Hasselbalch equation predicts that H2 PO4H3PO by five orders of magnitude(100,000: 1) at pH 7.06. Likewise, the pKa of HPO4212.4, which is~five pH units above 7.06. Thus, the Henderson-Hasselbalch equation predicts that HPOP43by five orders of magnitude(100,000: 1) at pH 7.06 Review| Constants | Periodic Table A biochemical reaction takes place in a 1.00 mL solution of 0.0250 M phosphate buffer initially at pH 7.06 Acid (Proton Donor) Conjugate Base (Proton Acceptor) pKaKa(M) H3PO4 PhosphoricDihydrogen H+2.14 7.24 x 103 acid H2PO4 phosphate ion HPO2 phosphate ion PO4 3- Part B H2PO4 DihydrogenMonohydrogen +H 6.86 1.38 x 10-7 phosphate ion During the reaction, 3.40 μmol of HCl are produced.

In organic chemistry, the mechanism of an organic reaction is defined as a complete step-by-step explanation of how a reaction of organic compounds happens. A completely detailed mechanism would relate the first structure of the reactants with the last s…

Heterolytic bond breaking is also known as heterolysis or heterolytic fission or ionic fission. It is defined as breaking of a covalent bond between two different atoms in which one atom gains both of the shared pair of electrons. The atom that gains bo…

Solvents that are chemically polar in nature and are not capable of hydrogen bonding (implying that a hydrogen atom directly linked with an electronegative atom is not found) are referred to as polar aprotic solvents. Some commonly used polar aprotic sol…

Oxygen being an electron rich species with a lone pair electron, can act as a good nucleophile. Typically, oxygen nucleophiles can be found in these compounds- water, hydroxides and alcohols.

We are aware that carbon belongs to group IV and hence does not possess any lone pair of electrons. Implying that neutral carbon is not a nucleophile then how is carbon going to be nucleophilic? The answer to this is that when a carbon atom is attached t…
