The gas is then passed into the caustic potash burette, left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements.
The solution should be let out of the burette until the indicator changes colour and the value on the burette should be recorded.
In a titration system the analytical concentrations of the reactants at each titration point are obtained from the initial conditions, the burette concentrations and volumes.
The initial and final readings on the burette (prior to starting the titration and at the end point, respectively) should be recorded.
Typically, a titration is performed with one or more reactants in the titration vessel and one or more reactants in the burette.
Titrant is added to the sample by means of a burette.
The known solution should then be allowed out of the burette, into the conical flask.
First, the burette should be rinsed with the standard solution, the pipette with the unknown solution, and the conical flask with distilled water.
