Want this question answered?
Buffer solutions resist the change in PH
buffer solutions resists change in PH
to maintain constant ph
why is the pH of the meadium important in EDTA titration
At half titration pH=pKa (you need the pH from the graph of your titration, y axis) ph = pKa + log (base/acid) 10^-pKa = Ka Kw=Ka*Kb Kb=Kw/Ka Ka = Kw/Kb
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side

Phenolphtalein change colorless at pH < 8 to purple blue at pH > 8 to 10
using pH meter
Titration
The neutralization point in acid and base titration can be determined metrically using the PH meter.
No.
To maintain pH=10
