Hello, Where are the references to this test? Are they from AWWA, APHA and WEF?

[@haryanvibhajan001]

thanks a lot mam for providing us the best we can understand

[@Arya_095]

Mam toh badi sndar hai🥰

[@knowledgepedia8591]

Can you tell me mam which chemical or metal repulse needle ?

[@shaikshaboddin1365]

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.

[@dr.monikasujitchavan8039]

No.

[@dr.monikasujitchavan8039]

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

[@DevKumar-ku8yz]

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

[@GisliNairs]

Why multiple by 1000? I calculated my readings-> 15.5ml × 0.01M × 1000/ 10ml = 15.5 (whats the unit?)

[@dr.monikasujitchavan8039]

because calculated per liter. Therefore Unit is mg/lit

[@amitkamble574]

Very Nice Ma'am

[@Abandon_rishi]

[@pikuset9177]

Dear Mam, 50 ml water sample mai Buffer Solution agar 3 to 4 drop dalenge to same result ajata hai to why should we waste Chemical ? Please reply mam

[@rajankaranjekar1278]

Which solution You fill up in Burette

[@dr.monikasujitchavan8039]

EDTA, Ethylene Diamine Tetra Acetic Acid.

[@purabiborah9590]

How did you made the buffer..

[@dr.monikasujitchavan8039]

Using weak acid and its conjugated base. Using ammonium chloride and ammonia.

[@sesaiahnambur3407]

Thank you madam

[@legendary-9996]

Amma please reply if I use 10 ml water then how much buffer will i use?

[@dr.monikasujitchavan8039]

You can use half test tube.

[@sejallakhanpal8931]

Respected mam .pls may I know is distilled water is temporary or permanent water ??also tap water is temporary or permanent water??

[@dr.monikasujitchavan8039]

Water is not temparory or permanent. Pure/distilled water does not show any type of hardness.

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)

[@dr.monikasujitchavan8039]

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.

[@microbiologypractical6401]

Very nice ma'am Issh vala practical ki miju pdf chahiya???

[@rajumahajan8514]

Mam how much we have to take EDTA

[@dr.monikasujitchavan8039]

Are you asking the normality?

[@dr.monikasujitchavan8039]

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?

[@dimpupradevdp3085]

Mam can you explain principle too

[@dr.monikasujitchavan8039]

The Ca++/Mg++ ions cause hardness to water is combine with EDTA solution. The ml of EDTA used, determine the hardness of water.

[@dimpupradevdp3085]

Thanks mam ❤️

[@abhishekrajak2928]

Thanks mam

[@Anurag-fk3op]

Can anybody put the formula here for the calculation of hardness

[@dr.monikasujitchavan8039]

Total Hardness=ml of EDTA used*normality of EDTA*50*1000/ml of water used

Ma'am everything is ok but in ur lab the proper instrument is not there & u teach to students so at least u tell how to handle &. Use the instrument. If they fill the burette as like u then they break it daily.
