How do we know when the equivalence point is reached?

you can kind of see it when you’re adding NaOH for example, and the pH does not increase very much.. then afterwards it jumps when you pass the equivalence point.. that’s on lab though

Thank you
Victor Hugo Spitz (PID: 6236968)
01:05:02
or go by the indicators like the prof is now teaching
Melissa Rodas

Yesss you know you reached the equivalence point when pH doesn’t change even though you keep adding NaOH
Miguel Iniesta Leyva

well, yeah but that would be more like the end of the titration; the equivalence point is where the pH spikes like crazy
Victor Hugo Spitz (PID: 6236968)
01:12:53
yes, the jump is the eq point.. when the pH is constant , that indicates that titration ended basically..

man that lab was a nightmare; the CPU usage is insane for no reason

mine crashed multiple times.. i guess when the system tries to calculate the numbers for us, it crashes lol.. trashGrawHill

yeah, that lab is the definition of a ticking bomb
