In this lecture a practical demonstration of Complexometric Direct EDTA Titration has been explained. This is a direct type of complexometric titration in which analyte is ZnSO4.7H2O, while Ethylene Diamine Tetra Acetate (EDTA) is acting as titrant, while Solochrome Black Tea/Eirochrome Black Tea (EBT) is acting as an indicator. The end point of titration is sky blue color, which is actually the original color of the EBT indicator.

AOA!! kindly send the confirmation text of how we have done practical for notebook and Viva voice. as soon as possible

Respected sir ....... Before zn carrying +2 O.S state after the formation of the complex it's O.S state is neutral.......can we say that now complex is most stable due to chelation

[@zerocramchemistry1610]

Oxidation state will remain same, as you can see from the overall charge of the complex. The stability comes after gaining noble gas configuration and chelation definitely.

Is it direct titration?

[@zerocramchemistry1610]

Yes, it's even written on video title
