- Experimental observations show that thiocyanate (SCN- ), the conjugate base of thiocyanic acid (pKa = 1.1 at 25 °C), is quite soluble in neutral water at pH > 2. In the space provided below, explain this experimental observation. That is, why does SCN– readily dissolve in water when the pH > 2?Glutamic acid is a naturally occurring α-amino acid that contains acarboxy group in its R group side chain. (Glutamic acid isdrawn in its neutral form with no charged atoms, a form that does not actually exist at any pH.) a.) What form of glutamic acid exists at pH = 1?b.) If the pH is gradually increased, what form of glutamic acid exists afterone equivalent of base is added? After two equivalents? After threeequivalents?c.) Propose a structure of monosodium glutamate, the common flavorenhancer known as MSG.When BF3 behaves as a Lewis acid, the stability of the adducts with (CH3)2O, (CH3)2S, and (CH3)2Se decreases in the order in which the Lewis bases are listed. However, when the Lewis acid is B(CH3)3, the most stable adduct is that formed with (CH3)2S and the adducts with (CH3)2Se ad (CH3)2O are about equally stable. Explain the difference in stability of the adducts

Serine, for example, has pKa values of2.19 and 9.21. Using species such as acetic acid and ammoniaas models, suggest the origin of the two pKa values.(c) Glutamic acid is an amino acid that has threepKa's: 2.10, 4.07, and 9.47. Draw the structure of glutamicacid, and assign each pKa to the appropriate part of themolecule. (d) An unknown amino acid is titrated withstrong base, producing the following titration curve.Which amino acids are likely candidates for the unknown?A typical amino acid with one amino group and one carboxylic acid group, such as serine can exist in water in several iconic forms. Suggest the forms of the amino acid at low pH and at a high pH. Amino acids generally have two pKa values, one in the range of 2 to 3 and the other in the range of 9 to 10. Serene, for example, has pKa values of 2.91 and 9.21. Using species such as acetic acid and ammonia as models, suggest the origin of the two pKa values. Glutamic acid is an amino acid that has three pKa’s: 2.10, 4.07, and 9.47. Draw the structure of glutamic acid and assign each pKa to the appropriate part of the molecule. An unknown amino acid is titrated with strong base, producing the following titration curve. Which amino acid are likely candidates for the unknown?
