Please tell you have mentioned that burette reading of blank as 11.1 and burette reading of sample 10.5.The fact is that higher burette reading means higher COD.
When Burette reading of blank is high it means its COD is high,which in turn means blank sample has higher organic content and incubated sample has low burette reading and low COD

[@arvindthakur8840]

This is for your clearance: - please note that this is kind of back titration method. suppose you have some organic matter in the sample which shall be completely digested by some amount of K2Cr2O7, and surplus Potassium Dichromate shall be titrated with the FAS for calculation. Now in blank sample there is no impurity which means whole Potassium Dichromate is to be titrated with FAS and consumed more in Blank. that's why Blank reference is also considered in in the testing.
hope this will help you.

Sir have a question . Your Burrett reading is approx 10 to 11 how can possible this in two different normality of solutions 0.25 and 0.1N.

[@pankajkumar2210]

Thanks 🙏👍🙏👍

[@vai88888]

After digestion kitna DM water add kiya?

[@sokunlehakeem]

Can it be done in English? Also is it compulsory to digest the sample? Why can't we titrate it direct

[@shikhajha4035]

Sir is there no need of COD digestor for the process to occur

[@haripatel9468]

Thank you sir !

Sir mera blank hi green ho rha hai kya problem ho shkti hai please reply

Sir BOD,TDS,PH,DO,etc test ka video pura with regent and calculation ka banaye

[@bhanu_sangita]

Bilkul sir aapka video bahut hi helpful hai.
Plz above topic pe bhi video banaiye.

[@zishan396]

My sample titration always exceeds blank sample by this method. Y this error occurs

[@shivamdiwakar4610]

Good morning sir, mere pass pure sulphuric acid hai ,mujhe 98% concentrated sulphuric acid bnana hai kaise bnaye ,plz help me sir or anyone

[@aquazoneengineering3556]

Purity of Sulphuric acid is 98%, you don't have to do anything. It is already 98% concentrated.

[@shivamdiwakar4610]

@@aquazoneengineering3556 okey thank you so very much sir

[@shivamdiwakar4610]

Sir stp me COD ke liye 150 temp rkhte h for 2 hour but hmare COD digester me 100 tk hi temp h toh kitna temp rakhe ham

[@Digital_Guidance]

Dm water kya hota hai sir ne bataya tha 3:30 seconds par koi batayega?

[@aquazoneengineering3556]

De-mineralised water, aisa water jisme TDS less than 0.9 ho. And conductivity 1.2 .

[@chukwumaonyeka29]

Please, how is sample dilution 10?

[@bhavikamehta1434]

Kya iske reference ka link bhi upload kar sakte hain please?

Why ...we take 8000....what is it's mean

[@mrmaniar1555]

What if we don't heat for 2 hour so the results will be higher or lower than actual results

[@aquazoneengineering3556]

Could be any of them, most of the time it may show higher then actual, because digestion would not take place properly.

We will share very soon.

aap 98% h2so4 without hand gloves addition kar rahe ho or pure video me aapne kaha bhi hand gloves nahi pehna.
#safetyfirst
aapko lab safety ke bare me padhne ki jarurat hai..
ye video ko dekh ke lab chemists per galat impact aa sakta hai.
