Hello, in this question we need to explain that when we do titration, why it is important to let out a little amount of titrant before reading the initial volume of our burret.
00:30
So the first option is given that because it is likely that the budate had chemicals on the inside that were washed to the bottom of the burrette, when the type, tight trend was added.
00:54
So this is removed them.
01:00
So this is the first option is not correct because when you start our titration before titration we watched the good at already with our tight trend and after that we poured the tightrend to make up the initial volume.
01:36
In the second option it is given that the titrant is more concentrated in the tip of the burette so by letting some out right before you begin the titration normalize the concentration.
01:56
Option 2 is also not correct as we know that the concentration of titrant is almost uniform in every part of the titan solution.
02:15
In the third option, it is given that any undesolved particles in the titrant will fall to the bottom of the burette.
02:30
So this removes them before they impact our titration.
02:38
Option 3 is also not correct because when we use our titan solution, we use the uniform titan solutions...
