- Hoping for solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced. Kriel just discovered a new protein, Krielase and for it not to unfold and lose its function, he realized that the protein needs to be constantly immersed in a pH = 6.50 solution. He is therefore interested in preparing a 50 mL 0.08 M pH = 4.50 buffer to contain the protein. He listed down the pure acids available to his disposal, and also looked for their acid dissociation constant (Ka) values. Acid Name Ka1 Ka2 Ka3 Nitrous Acid (HNO2) 4.00 x 10-4 N/A N/A Acetic Acid (CH3COOH) 1.76 x 10-5 N/A N/A Ascorbic Acid (HAsc) 7.90 x 10-5 1.60 x 10-12 N/A Phosphoric Acid (H3PO4) 7.52 x 10-3 6.23 x 10-8 4.28 x 10-13 A. Identify which weak acid system is best to use in preparing the buffer? Why? B. Identify the species which will make up the buffer system?…! ( give ans with explanation , do both vey easy )( plz give correct ans with explanation )
- Provide detailed (arrow pushing) mechanism for the following reaction, draw all importantresonance structures for the intermediates. Where appropriate indicate Lewis acid and base foreach step, and whether they are also Bronsted acids and bases (LB/BA, LA/BA etc.) Indicate thenumber of steps in the mechanism and the number of intermediates.( asap with explanation give typed ans )Why is ths the correct order in terms of reactvity. I throught fluroine has more electronegatvity so its the most acidic.
