EXCELLENT for reashers I request separate file for the list of chemicals glassware reagents preparation .It will be highly useful for researchers please highlight the use of salicylic acid with regards prof.T.Rajukannu

Would it be permissible according to those standards to just keep working with 0.1N of sulfuric acid?

Hello, I also need a video for acidity and hardness based on APHA, AWWA, and WEF. By the way, in the 23rd Edition of Standard Methods for the Examination of Water and Wastewater from APHA, AWWA and WEF, they also use other indicators like bromcresol green (I don't know why) and other things. Are there any videos available that explain acidity and hardness according tho those standards?

Great sir 🖤🖤🖤

Good day what is your reference in the computation of the dissolved oxygen

Informative video i learnt alot but i wanna ask.. In any station if one or more metal have monitor values < 0.005 or <0.02 or below then detectable limit. Does we consider any value below than 0.005 or 0.02 or half detection value (0.0025 or 0.01) or we take zero?

1.05 kya h

A course at a time?

Mi value should be in milligrams per liter or micrograms per liter?

TY so much

Thank you sir!

Sir…. Since we are taking ideal value for pH as 7 and DO as 14, what is the formula to Calculate the vn/an of DO value??? Would be happy to hear the reply

Very nice presentation sir. But one thing i am getting vaues of F1,F2 are positive but F3 value is negative. This means that acording to calculation basis water status is good but getting CCME VALUE IS 25 WHICH INDICATES WATER HAS POOR QUALITY. PLEASE can you clarify this doubt sir.please

Sir is sodium hydroxide necessary for preparation of sodium thiosulphate for determining dissolved oxygen in water?

In a station, if a metal is not detected (<0.05 for example as the concentration), do you put a zero for that concentration?

Thanks for the information and guide on how to perform the calculations. However, you've broken one of the worst rules in chemistry and that is not having an form of units on this. How are you dividing ml/ml and coming out with mg/L. It doesn't make sense without you including units in this.

What if we have morethan two sites.

Thank you so much sir.... 🙏🏼. Easy to understand.... 😊

Will we not get the certificate if we dont submit the assignment

Wonderful explanation. Thanks a lot.

Thank you sir!

Hello sir, you have explained in a very easy way, but sir i am unable to get these quality rating charts. from where we can get these charts ?

Interesting pls another video on EF,CF,CD if u can

Can you tell how to make standard for estimation of nitrate and phosphate

Thank you very much for your efforts. I have a question about the number and type of parameters that can be used to calculate this index. Here, you have used 10 parameters.

Exam is online or offline

Xcellent

Sir can u pls upload video for COD and chloride

Dr. Eugene, I have no words to thank you for this video! My name is Ana Carolina, and I am watching this video in September 2024. I am a Brazilian biologist pursuing a master's degree in environmental engineering. My thesis depends on this index to move forward. I couldn’t manage to do it on my own nor find anything on the internet that helped so clearly. Thank you so much, truly!

If i fail to register before the end registeration date then would i get a re in the subject ,it is an elective subject?????????????????

Very very very good explanation ❤❤❤❤❤❤

I have just cleared my 12th grade and yet to join a college, but i am not able to fill the personal details without entering college details,is there any other way arond, plz help

Could you please explain how to attend classes for the enrolled classes ?

Can it be used for soil samples?

Hello. The pH standard values and the temperature standard values are a range. What then do we take as the standard? the upper value, mid point or lower value? Can someone please clarify?

Excellent explanation

Helpful. Thk u sir

Thank you so much... excellent

Sir, put the fluoride, chloride, sulphate, nitrate,iron, test video

So helpful sir .....thank you very much

User ID aur password bhul gaye to kya kar sakte h

Thank you sir ....it will really helpfull

Thanks so much it helped me to understand a sampling frame 🎉🎉🎉

TENQIU VERY MUCH MAI FREND

Big thanks Dr. Eugene for your efforts> Could you please share the MS Excel file?

Thank you, can you please give me the excel file?

Which caste certificate i have to upload state or Central

Dear sir plz send me COD estimation
