Pipetting Technique Laboratory technique for using a volumetric pipet. Calculate the concentration of the sodium hydroxide solution. The main reason that EDTA is used so extensively in the standardization of metal cation solutions is that the formation constant for most metal cation-EDTA complexes is very high, meaning that the equilibrium for the reaction: lies far to the right. Color change shows that the indicator has been displaced (usually by EDTA) from the metal cations in solution when the end point has been reached. This product is available in a 1 oz.
