solution of potassium hydroxide using standard hydrochloric acid Theory . Introduction: Titration is a procedure used in chemistry in order to determines the molarity of an acid or a base. In the other words‚ it is also consider as acid-base neutralization reaction (Darrell D. Ebbing 1976). A chemical reaction is set up between a know volume of a solution of unknown concentration and a known volume of a solution with a known concentration. The relative acidity or basicity of an aqueous solution

a substance of a solution which could be an acid or a base. A titration curve of an amino acid is a plot of the pH of a weak acid against the degree of neutralization of the acid by a standard base. Lysine‚ glutamine‚ glutamic acid‚ and histidine were analyzed in this experiment. These amino acids were selected because they have quite similar molar masses (155.1 for histidine‚ 146.2 for lysine‚ 146.1 for glutamine and 147.1 for glutamic acid) so that equal masses of the amino acids will make solutions

A titration is a method where a solution of known concentration is used to determine the concentration of an unknown solution. Typically‚ the known solution is added from a burette to a known amount of the unknown solution until the reaction is complete. Knowing the volume of the known solution added allows the determination of the concentration of the unknown. Often‚ an indicator is used to usually signal the end of the reaction‚ the endpoint. Concentration is the abundance of a constituent divided
