Welcome. SoftRide Trailers is the home of the SoftRide Suspension System. The First Air Ride Suspension system made exclusively for light and medium duty trailers. Featuring an adjustable â Air Ride â that allows the operator to raise and lower the trailer on command !
I2(aq) + 2S2O32-(aq) â 2I-(aq) + S4O62-(aq). The copper(II) ions can also be titrated against a solution of EDTA in a complexiometric titration. The indicator to use is called Fast Sulphon F. An acid-base titration would not at first sight seem to be very helpful.he blue colour of your solution is caused by the Cu2+(aq) ion. The more concentrated the solution the more intense the colour is. You can make up known concentrations of copper(ll) ion solution and use a colorimeter to produce a copper(ll) ion concentration/absorbance calibration curve.
EDTA forms an octahedral complex with most 2+ metal cations, M 2+ , in aqueous 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:eactions for Complexometric Titration [edit]. In theory, any complexation reaction can be used as a volumetric technique provided that: 1  the reaction reaches equilibrium rapidly after each portion of titrant is added.
