DETERMINATION OF TOTAL HARDNESS OF WATER SAMPLE USING STANDARD EDTA SOLUTION (SAVI,SVIT,VTU) 

Mom I would like to thank from my deep heart,b/c it is a part of my research to get information.

Nicely explained in a manner that i could understand it easily. Thank you.

Mam better to add 2 drops of the eriochrome black to the conical flask before titrating

Very tough experiment hopefully I don't get it for practical tomorrow

Mam how you are going to check whether the resulting volume of EDTA is correct or not ?
