In place of EDTA we can use other reagent or not. And also why we add the pH buffer what is it's range. After completion of titration what is the range of pH in a conical flask.
The buffer solution used in complexometric titration has pH 10. This is necessary to carryout reaction between metal ion and EDTA which is possible in basic solution. One more thing, To get the desired colour change
Why are there two steps, Part 1 and Part 2? Also, is the ZnSO4 solution a standard for ward water? PROCEDURE:- Part 1 :- Determination of Molarity of EDTA (Standardization of EDTA solution). 1. Pipette out 25ml of standard ZnSO4 solution in a conical flask 2. ½ test tube buffer solution (NH4Cl + NH4OH, pH= 10) 3. add 1-2 drops of EBT indicator. Wine red colour will appear. 4. Then titrate with EDTA solution. At the end point colour changes to clear blue. End point = (Xml) PART-II:- Determination of Total Hardness 1. Pipette out 25ml of hard water sample in a conical flask 2. 1/2 test tube buffer solution 3. 1-2 drops EBT indicator, wine red colour appears. 4. Then titrate with EDTA solution. At the end point, colour changes from wine red to clear blue. End point = (Y ml)
As per your procedure: Part I : calculate the exact normality of EDTA by titrating it with stadard ZnSO4 solution. Part II : Determination of hardness of water.

Going to give my practicals in 2 hrs and revising from this video
Thankyou so much.....
One of the best teacher in my life 👍👍😍
Your teaching style is very down to earth mam thanku for this video it's stay blessed mam ❤️
very nicely explained Dr sahib.
Very well explained..
Outstanding ma’am ✨
Best video mam 👍 tomorrow is my practical and my college hasn't taught any experiment 🥺 your videos are very helpful 🙏
Best luck for exam.
Tomorrow is my external your video help me a lot thankful to you mam by heart ❤❤❤❤❤❤❤❤❤❤ I know that much heart is less but try to understand

Very Nice Ma'am
Can you tell me mam which chemical or metal repulse needle ?
Thanks 🙏❤️♥️

@@dr.monikasujitchavan8039 hmm ok mam
30 gram weight 50 ml water 50ml ethanol or eske baad water bath rakh de melt ke baad pH buffer solution 25 ml copper sulphate se titration kre
Why multiple by 1000? I calculated my readings-> 15.5ml × 0.01M × 1000/ 10ml = 15.5 (whats the unit?)
because calculated per liter. Therefore Unit is mg/lit

Very nice mam
Thank you
Amma please reply if I use 10 ml water then how much buffer will i use?
You can use half test tube.
Respected mam .pls may I know is distilled water is temporary or permanent water ??also tap water is temporary or permanent water??
Water is not temparory or permanent.
Pure/distilled water does not show any type of hardness.
Which solution You fill up in Burette
EDTA, Ethylene Diamine Tetra Acetic Acid.
Which college experiment?
These experiments are from FYBTech syllabus.
Sanjay Ghodawat University, Kolhapur.
Students should wear *LAB COAT* also
Yes dear😊
Why are there two steps, Part 1 and Part 2?
Also, is the ZnSO4 solution a standard for ward water?
PROCEDURE:-
Part 1 :- Determination of Molarity of EDTA (Standardization of EDTA solution).
1. Pipette out 25ml of standard ZnSO4 solution in a conical flask
2. ½ test tube buffer solution (NH4Cl + NH4OH, pH= 10)
3. add 1-2 drops of EBT indicator. Wine red colour will appear.
4. Then titrate with EDTA solution. At the end point colour changes to clear blue. End point = (Xml)
PART-II:- Determination of Total Hardness
1. Pipette out 25ml of hard water sample in a conical flask
2. 1/2 test tube buffer solution
3. 1-2 drops EBT indicator, wine red colour appears.
4. Then titrate with EDTA solution. At the end point, colour changes from wine red to clear blue. End point = (Y ml)
As per your procedure:
Part I : calculate the exact normality of EDTA by titrating it with stadard ZnSO4 solution.
Part II : Determination of hardness of water.
Mam how much we have to take EDTA
Are you asking the normality?
The titration of water sample with EDTA inpesence of EBT indicator, we have to add EDTA till we get the colour change i.e. wine red to sky blue?
Institute ka adress send me
Mam can you explain principle too
The Ca++/Mg++ ions cause hardness to water is combine with EDTA solution. The ml of EDTA used, determine the hardness of water.
Thanks mam ❤️
No Tamil Explain 😢
LEGENDS ARE WATCHING SOMEWHERE ELSE🌚🌚🫵🫵🫵🫵🫵🫦🫦
Mam institute ka adress send me please
Sanjay Ghodawat University, sangli kolhapur highway, Atigre, kolhapur
Can anybody put the formula here for the calculation of hardness
Total Hardness=ml of EDTA used*normality of EDTA*50*1000/ml of water used

@@dr.monikasujitchavan8039 mam upper 50 kya he

I think you are want to change your camera man
EDTA Na2 ???
Yes.
EDTA in the form of Disodium salt of EDTA
I can understand I don't like it mam
