Estimation of calcium and magnesium in a given water sample

[@pradeeppawar1925]

Thank you for sharing this experimental procedure but Sir can you please tell me how much normality of EDTA it was?? Nd that 2 mL sodium hydroxide was diluted or not and if diluted then at what measurements?? It will be really helpful and grateful if you let me know😊

[@JeetendraSingh-jq4mf]

Bahut badhiya sir Ji

[@aanchalsaklani456]

At last for magnesium 334 value comes from. Where ?

[@gungunsinghbihari4047]

Mujhe v training Leni h apse kya krna parega plz reply

[@jayalalitathakur5570]

Very nice sir

[@subratabag11]

Sir will the mg not interfere? In only calcium calculation?

[@omprakashdashora4911]

Bachhe ko titration karne ka sahi tarika sikhaye, muroxide ki jagah P&R indicator better hota he because color change from wine red to Blue

[@pradeepraj3761]

what is the range of EDTA and NaOH?

[@swathikumar100]

Sir how much ml ETDA SOLUTION TAKEN IN burette.

[@premveerjaat6088]

Konsa method use kiya h

[@reverbplace7850]

Amazing!

[@mohd.junaidsiddiqui5059]

magnesium ka method share kariye sir and formula bhi kis tarah nikalte h magnesium test in water

[@muzammilhussain5013]

Please explain the factor (400.5 and 1.05) used in formula is this factor remain constant for all sample variation or it can deviate with ml of sample. Thank you we are waiting for your reply please urgent it help us a lot.

[@gyaanprayogshala]

Constant not vary

[@muzammilhussain5013]

@@gyaanprayogshala thanks a lot

[@letscrackit2206]

Very nice👍

[@shameemahmed3714]

Calculation formulae explain kijiye sir 400. 5 ? , 1.05 ?

[@thodabandihareesh875]

Some problem why put that values

[@ishwarkoradi1399]

bhai saab mein khabi bhi nahi dehka ki bureet se chemecial squzer se nahi muhse liya jata hai. That institue is in next level.

[@shameemahmed3714]

Kon said indicator use kiya sir reply

[@gyaanprayogshala]

Mueroxide .2g

[@URKCEHinoSuu]

Watch out! That teacher might have been positive with Corona before the pandemic even started! All in all, thank you sir! I really enjoyed and understood the lesson, despite it being in hindi.

[@_EktaSharma]

Sir explain 400.5 ? 1.05 ?

[@ravalaman1664]

He puts wrong Cal is BR*20.05*.0.02*1000/50 Where 20.05 is calcium equivalent 0.02 is EDTA normality 1000 is converting to ppm And 50 is taken volume of sample And more add P&R indicator batter then buroxide

[@mohd.junaidsiddiqui5059]

mehtod and proses bhi comment me share kare

[@devadarsh7962]

Hardness हमेशा as caco3 निकाला जाता है

[@yogeshrautel9075]

Sir formula expl.kijiyna

[@Bipinkumar-kt1pr]

Galat titration karwa rahe ho aap

[@liaqatali525]

Kha belkul ghlat ha.

[@shameemahmed3714]

Is formulae m 400.5 and 1.05 kya h aur kaha see aaya sir reply please

[@shameemahmed3714]

Aap reply kyon Nahi kartey

[@unknown1725]

Best students 😂😂😂

[@devadarsh7962]

What is नार्मल of EDTA

[@gyaanprayogshala]

Normality of EDTA IS 0.01N

[@gyaanprayogshala]

[@gungunsinghbihari4047]

Sir apna number denge
