A reagent, termed the titrant or titrator, [2] is prepared as a standard solution of known concentration and volume. The titrant reacts with a solution of analyte (which may also be termed the titrand [3]) to determine the analyte's concentration. The volume of titrant that reacted with the analyte is termed the titration volume.
Differences in the temperature between the titrant and the titrand; Evaporative losses from the surface of the rapidly mixed fluid; Heats of solution when the titrant solvent is mixed with the analyte solvent; Heat introduced by the mechanical action of stirring (minor influence); and; Heat produced by the thermistor itself (very minor influence).
Titration is a family of techniques used to determine the concentration of an analyte. [8] Titrating accurately to either the half-equivalence point or the endpoint of a titration allows the chemist to determine the amount of moles used, which can then be used to determine a concentration or composition of the titrant.
E sol is the potential drop over the test solution between the two electrodes. E cell is recorded at intervals as the titrant is added. A graph of potential against volume added can be drawn and the end point of the reaction is halfway between the jump in voltage.
A Gran plot (also known as Gran titration or the Gran method) is a common means of standardizing a titrate or titrant by estimating the equivalence volume or end point in a strong acid-strong base titration or in a potentiometric titration.
MicroCal. VP-ITC in a glove box. In chemical thermodynamics, isothermal titration calorimetry (ITC) is a physical technique used to determine the thermodynamic parameters of interactions in solution.
Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.
