10 % dilution factor lagaye.. 10 ml sample ko 100 ml distilled water me dilute kare aur usme se 20 ml sample COD vials me Dale.. calculation me 10 se multiply kar dena

Sir, I really liked your method of teaching. ❤
Bhut badiya information for lab chemist.
बहुत ही शानदार तरीके से समझाया है सर आपने बहुत बहुत धन्यवाद 😊
best explanation with practical experiment
Nice information sir aap bahut achhe tarike se samjhate ho 😊
Chemical oxygen demand treatment water ka main parameters hai. Thanks for video.
Very helpful video for new lab chemist.
Thanks a lot
Nice video
Thanks
Bahut badiya jankari laboratory opretor ke liye
Thanks
Nice 👍
Thanku so much Sir It was great explained 😊
Very good method for COD
Super
Helpful vdo
Very helpful video for new lab chemist 🧪👍👍
👍👍👍👍👍👍
Very helpful video. Thanku so much. Aap aur bhi chemist ke liye video banate rhe sir.
Beautiful lab
Very helpful sir
I like it. Pura clear ho gya. Sir please aap is method ki puri process including chemical preparation pdf upload kr do na 🙏

Thanks 🙏
Sir Phosphorus kaise nikaalte hai video banakar dal do please
❤❤❤❤
Nice
Very nice sir ji
Weldone 👍👍
Badiya video
👍
Thank you so much sir😊bahut axxa hai
Well done sir
Thanks sir .. nice video.
Very nicely explain 👍👍

Potassium dichromate priped se bhi dal sakte h buret ki kya jarurat h
Very good ❤
👍👍🥰
Nice sir ❤
Sir please ae video me jo extra music sound hai vo na dala kare usse apki voice clear nahi aa rahi kuch time🙏🙏
Nice ❤❤
Best information sir ❤
Very helpful bro.
Ok thanks
How to check bod
And Do testing per bhi video
Wait the video will be uploaded soon..
Please subscribe our channel
@@EnviroTechSupport710 OK thanks
Sir high cod pr video bana dijiye
High COD par video jld upload hoga, dilution factor pura complete krwaunga.
Bhut badiya sir.. BOD ke upar bhi ek video bnaiye.
Sir please make video on bod practical 🙏
Ok wait
@@EnviroTechSupport710 tnx sir
Faecal coliform me kya kya chemical use aate Hain
Sir faecal coliform ki testing kese hoti hai
All the best ❤
Sir dilution factor kya hota he plz sir thoda ditel me samjha dijiye
Sample ko dilute krte hai .. dilution factor par video alg se upload hoga
@@EnviroTechSupport710 thankyou sir
Sir, 10 ml k2cr2o7 hi kyu use kiya..uski calculation bata sakte ho kya ?
🇮🇳Excellent explanation 🇮🇳👍🤍👍
Ek bar high cod ki bhi procedure bnao
Okk
Formula me •1 normalty lagaye hai uske jagah per hum •25 le sakte hai sir tell me pkz
Dilution factor ka formula bhejo sir 10 weight of sample ki jgh Lena hai kya kha lena hai
COD ka result aa rha hai usme 10 se multiply kar dena hai agar 10 ml dilution factor liya hai .
@@EnviroTechSupport710 weight of sample 20 hi Lena hai kya fir 10 dilution factor lgaye to
Weight of sample nhi hota hai, ml of sample hota hai, ml of sample 20 hi lena hai, isme 10 se multiply karna hota hai 10 dilution factor lete hai to.
@@EnviroTechSupport710 dilution factor se sep inlet ka 1005 mg/ltr AA rha hai shi hai kya burette reading -19.35,blank-21.8, Normality -0.1026,10% dilution factor lgake
Right 👍👍
Kayse lgaye dilution factor
Can you make a video using APHA 5220D method? (Closed reflux colorimetric method) it will be very helpful for me. Please😢
Dilution factor kase use karte ahe
Haye my fv❤❤
Outlets ka sample me dixtel water nahi add karna hota hai kya sir,, 20 pura sample hi add kiye hai outlets me
Outlet ka COD 200 se jyda aa rha ho to dilution factor lga sakte hai
@@EnviroTechSupport710 sir jab outlet ka solution me dixtel water add nahi karna hota hai
@@EnviroTechSupport710 dilutiin factor kya hai sir
Formula hota hai distilled water add karne ka.. dilution factor ki study Karo.
Burette me pehle se Potassium di chromate tha kya?
Yes, use hone ke bad burettes me hi chemical bacha rhta hai
@@EnviroTechSupport710 ohk Ta 🥰
Welcome
Sir please tell what was the sample reading after titration against FAS
Blank reading is something like 24.5 to 26.5 ml... And the reading of the sample is according to COD.
@@EnviroTechSupport710 So Sir What was the COD
Please Watch the full video, I have explained it in full detail.
Sir , potassium dichromate10 ml +20 ml outlet sample + h2S04 30 ml than mixing after colour is green ,
What should do than ???
Yes
Video me details me bataya hua hai
Sir ek BOD ki video bhi bna do
Aaj upload hoga
Salam sir
Sir bod ke b video bana den same like cod
Ok next week upload krunga, channel ko subscribe kre.
Need Fecal coliform test information
Tamil explanation videos pls
Sir pls tell me what are the mistake one sample two report it is not near .for example: reading 2.1and another 3.4 what's the reason.
Take the sample with accuracy.
Kuch isme blank se jyada q lgti hai sample ki reading
Bod kab btayenge
Sir 80 ml distil water lekar cod samle condensor wash karge
Yes
Sara chemical adha dalte h to bhi same result ata h aisa kyo
Jaise sulphuric acid 15 ml dichromate 5 ml
Sir outleat water sample mey distilled water mix karna hota hai
Yes, COD jyda aa rhi ho to dilution factor lgana hota hai
Chloride jyada honese cod me problem aa sakti hai kya sir
Nhi.. chloride alg parameters hai aur COD alg.
@@EnviroTechSupport710 Mera cod ka sample fail nhi hua lekin turbid ho gaya digestion ke bad
Bod ki procedure btao
Ok wait
Sir isko ppm mey kaise calculate kare
Result PPM me hi aaya hai.
Ok
Sorry sir
Cod kitne se kitna hona chahiye
Sir abhi mey fresher hu
COD 250 ppm , maximum limit
Sample kitna jayega ye kaise pata kare
Cod jyada rha to philehi green colour ata hai to kya kre sir
Dilution factor lagaye..
@@EnviroTechSupport710 wo kayse nikalte hai
10 % dilution factor lagaye..
10 ml sample ko 100 ml distilled water me dilute kare aur usme se 20 ml sample COD vials me Dale.. calculation me 10 se multiply kar dena
@@EnviroTechSupport710ok sir thank you
@@EnviroTechSupport710mtlb sample aur distilled water dono pkdke 100 ml hona chahiye
Bod ki video bnaye
Ok wait
COD test 150 C temperature Par kiya jata he
100 se 150°c tak temperature rakh sakte hai
Sorry for the correction of your sentence. As per IS 3025 and APHA method, the COD test should be performed at 150±2°C.
@gohelmilan3740.. right 👍. There will be no variation in COD result, I have set it at 150°c also.
Sir cod kitna hona chahiye aap bata sakte ho
Less than 250 mg/L
Plz reply
DF kab lete h
COD 250 se 300 ke something ho to sample fail ho jata hai, green ho jata hai, us conditions me DF lena hai.
Thanks
.
Cod shi hai ki galat ye check krne ke liye kya Krna pdta hai
Accuracy ke sath sample prepare kare..
Sir 2 cod lgaye ekhi sample ka dilution factor lgake dono ka alg alg aya to kya kre
Aur dilution 100 me 10 % ka kiya aur bhut jyada cod thi high to whase 1 ml dalke 19 ml distilled water dala
Kitna aaya ?
