[@hemanthgowda9183]

Sir you have not added NH3 TO edta sample...

[@alltop109]

Magic

[@DrChandrashekar-kp5gu]

Yes a real magic 😂

[@manasvigowda5005]

True

EDTA is used for titrating no need to add buffer solution

Watching before 1 hour to exam

[@drchandrasekharn]

Thank you
All the best

What is the use of NH3-NH4Cl buffer sir

Disodium salt of EDTA dissolves in Water

[@Piyushshah618]

sir while preparing the standard solution can we add 5ml of ammonim sloution also for dissloving of crystals

[@drchandrasekharn]

Yes you can Thank you

Sir what about removal of hardness using ion exchange method

[@drchandrasekharn]

Thank you it is possible

How do professors find the exact titrate value without doing the experiment sir? Can you pls tell us if there's any formula for it
