WebDec 30, 2013 · In order to separate compounds from each other, they are often chemically modified to make them more ionic i.e., convert a carboxylic acid into a carboxylate by adding a base. Standard solutions that are used for extraction are: 5 % hydrochloric acid, 5 % sodium hydroxide solution, saturated sodium bicarbonate solution (~6 %) and water. WebMar 31, 2011 · Values of the ionization constant of acetic acid in H(2)O and D(2)O (K(HAc) and K(DAc)) and the deuterium isotope effect, ΔpK = pK(DAc) - pK(HAc), have been determined from T = 368 K to T = 548 K at p = 20 MPa, using a flow-through ac conductance cell built at the University of Delaware.

WebJan 9, 1981 · Abstract. A method for the accurate determination of d -amino acids in protein/peptide samples has been developed. This method differentiates d -isomers formed during protein acid hydrolysis from the initial contribution of the sample. To this effect, the hydrolysis is carried out in deuterated hydrochloric acid.
