Interpretation:
Appropriate products are to be drawn for the given proton transfer reaction with curved arrow notation.
Concept introduction:
In a proton transfer reaction, a proton is transferred from a Bronsted-Lowry acid to a Bronsted-Lowry base in a single elementary step in which one bond is broken and another is formed simultaneously. The curved arrow notation shows the movement of valence electrons, not atoms. The movement of two valence electrons is shown by curved arrow. To represent bond breaking, the tail of the arrow originates from the center of a bond whereas to represent bond formation, the head of arrow points to an atom which forms the new bond, that is, bond or the region where the bond is formed if the new bond is a
bond. The conjugate acid is the species that the base becomes after gaining a proton, and the conjugate base is the species that the acid becomes after losing a proton.

Answer to Problem 6.38P

Explanation of Solution
The curved arrow notation for the given proton transfer reaction is shown below:
In a proton transfer reaction, a proton is transferred from the Bronsted-Lowry acid to the Bronsted-Lowry base. The movement of two valence electrons is shown by curved arrow. The head of the arrow pointing to the atom shows the transfer of valence electrons to form a new single bond. In the above reaction, one curved arrow is drawn from the lone pair on O to the H on the other reactant, so it illustrates the formation of a new

The same ion has a diffusion coefficient of 9.5 x 10-6cm2s-1. If this ion is separated from cations by CZE with a 75cm capillary, what is the expected plate count, N, at an applied voltage of 15.0kV? Under these separation conditions, the electroosmotic flow rate was 0.85mm s-1 toward the cathode.

A commercial oxygenated bleach is much safer to handle and less likely to ruin your clothes. It is possible to determine the amount of active ingredient in an oxygenated bleach product by performing a redox titration. The balance reaction for such a titration is: 6H+ +5H2O2 +2MnO4- à 5O2 + 2Mn2+ + 8H2O If you performed the following procedure: “First, dilute the Seventh Generation Non-Chlorine Bleach by pipetting 10 mL of bleach in a 100 mL volumetric flask and filling the flask to the mark with distilled water. Next, pipet 10 mL of the diluted bleach solution into a 250 mL Erlenmeyer flask and add 20 mL of 1.0 M H2SO4 to the flask. This solution should be titrated with 0.0100 M KMnO4 solution.” It took 18.47mL of the KMnO4 to reach the endpoint on average.
