- Leucine is an amino acid with this Lewis structure: Write the Lewis structure for the zwitterion form of leucine.A substance that functions to prevent rapid, drastic changes in the pH of a body fluid by changing strong acids and bases into weak acids and bases is called an: a.salt. b.buffer. c.enzyme. d.coenzyme.7. Describe a buffered solution. Give three examples of buffered solutions. For each of your examples, write equations and explain how the components of the buffered solution consume added strong acids or bases. Why is buffering of solutions in biological systems so important?
- The reaction just described is reversible. Deprotonation of the conjugate acid of an organic base by water provides another example of simultaneous making and breaking of sigma bonds. Thus, in the deprotonation of anilinium ion by water, the base is water, which has unshared electrons on the ________ atom. The acid is ________ ion. A pair of ________ electrons on the oxygen atom of water is pushed toward the ________ atom. Simultaneously, the pair of ________ electrons between the hydrogen and ________ atom of the anilinium ion is pushed toward the ________ atom. Thus, the oxygen- ________ sigma bond is made and a hydrogen- ________ sigma bond is broken. The nitrogen atom, which possessed a positive charge, is now ________, and the oxygen atom, which was neutral, now possesses a formal ________ charge.The sec-butyl cation can react as both a Brnsted-Lowry acid (a proton donor) and a Lewis acid (an electron pair acceptor) in the presence of a watersulfuric acid mixture. In each case, however, the product is different. The two reactions are as follows: (a) In which reaction(s) does this cation react as a Lewis acid? In which reaction(s) does it react as a Brnsted-Lowry acid? (b) Write Lewis structures for reactants and products and show by the use of curved arrows how each reaction occurs.Please plot this in excel as a smooth line scatter chart with the Volume on the X axis and the pH on the Y title it Volume vs pH title the both axis Volume of sodium hydroxide pH 0.00 5.00 1.00 5.96 2.00 6.26 3.00 6.41 4.00 6.64 5.00 6.77 6.00 6.88 7.00 6.97 8.00 7.07 9.00 7.16 10.00 7.25 11.00 7.35 12.00 7.43 13.00 7.54 14.00 7.65 15.00 7.77 16.00 7.91 17.10 8.12 17.20 8.15 17.30 8.17 17.40 8.20 17.50 8.23 17.60 8.26 17.70 8.28 17.8 8.31 17.9 8.34 18.0 8.38 18.1 8.45 18.2 8.48 18.3 8.53 18.4 8.60 18.5 8.66 18.6 8.76 18.7 8.88 18.8 9.03 18.9 9.22 19.0 9.39 19.1 9.58 19.2 9.70 19.3 10.00 19.4 10.22 19.5 10.46 19.6 10.60 19.7 10.72 19.8 10.81 19.9 10.91 20.9 11.42 21.9 11.63 22.9 11.77 23.9 11.88 24.9 11.97
