Brilliant. I can't believe I never thought of using my mouth to operate the graduated pipette. Just sip some of that sweet, sweet ammonia. I mean, who needs to see the volume reading anyway?
thank you sir, this video helped me a lot, you told the process in a simple way, i hope you put more videos which will be helpful to the students like us. very very thank you. superb
Allan J Martirez, the guy's assumption that elevated conductivity means salty taste can be misleading. Also depending on the pH of the water, sodium cyanide can be quite innocuous.
Sir, I thank you very much for the vedio, i have some doubt where did you find the preparing reagents procedures. bcoz i am seeing diffrent chemicals used for preparing reagents.
Sir, Please do not pippetout AMMONIA BUFFER and transfer the sample in to conical flask by using pippete and not measuring jar..Hope you oblize. .he presentaion is very excellent. suggetion by the SENIOR ANALYST in Govt of AP.
7:24 minutes; is it a good practice to suck the reagent to fill the pipette? Or should you use an aspirator? However, i've seen more. In my work place before, there is this guy who knows everything. When i asked him to determine if our water has conductivity, he tasted it first if it was salty. Sigh, how i wish i added sodium cyanide to the water first.
I don't actually get the part of adding distilled water to sample water.Yes both of them the temporary hardness has been removed.Instead he would have added additional boiled sample water instead of distilled water.
According to me, we shouldn't add distilled water to boiled and cooled water..since the volume will change but no salt is increased and this reflects in different answer for permanent hardness because hardness is also dependent on volume...i.e suppose there is equal amount of permanent hardness causing salt in two samples of hard water with different volumes then permanent hardness in ppm or mg/lit is different for both the samples...so instead off adding distilled water we can measure the amount of water remained after boiling and calculate with the same.
calculate the hardness and the concentration of chlorides in wastewater sample. Express your results in mg/L Volume of waste water sample = 0.15 Liter. Volume of AgNO, used for titration 225 ml. Volume of EDTA titrant = 8500 micro L Molarity of EDTA = 15 mM, Normality of AgNO, O.O5N...solve this problem
watch it at speed 1.5 u will thank me later
Diwash Poudel thanks
Diwash Poudel 😂😂😂😂
thank you
Tysm Diwash Poudel
😂😂
When was this video shot? Has such a soothing 90s vibe to it. Also, very explanatory and simple.
Even u watch at 2X speed...the vdo still seems to be slow😉
I'm over joy of your presentation and clear English. Thanks you.
I'm studying environmental engineering. I will always follow you sir.
observations table starts from 13:39
Calculations 14:45.
You know what we are searching for 😂😂
@@avi_dahiya yup 😁
Gorgeous explanation and content thank sir upload more lecture
Brilliant. I can't believe I never thought of using my mouth to operate the graduated pipette. Just sip some of that sweet, sweet ammonia. I mean, who needs to see the volume reading anyway?
Callistonian omg i can smell the ammonia emanating from the glass bottle already 😷
made my day
shit negro thats certainly stupid, even though some guy could do it wrong and get a bad moment
All the best ever TH-cam channel more more subscribers
Thank You sir, Explained Wonderfully (y)
Excellent illustration!
Thanks for this guide, it shall come in handy for tomorrow's midterm :)
How did you done it ?
I have never laughed so much! and the music....:)))
thank you sir, this video helped me a lot, you told the process in a simple way, i hope you put more videos which will be helpful to the students like us. very very thank you. superb
It is easy to understand .thank you sir
Watch it at speed of 2x it will help u to save your time....😀🔥
Thanks for this video 👏😴 Kal Practical hai mera.. saal bhar gya nahi Lab mein aur aaj ye mil gya Dhanyawad ❤
good and clean explanation sir ,thank you.
thanks for this video.. this helps me for practical exam
Very nyc teaching Will you thank u sir
You teach really very well sir 🙂
Allan J Martirez, the guy's assumption that elevated conductivity means salty taste can be misleading. Also depending on the pH of the water, sodium cyanide can be quite innocuous.
I wished you could explain the nutrient in water too, such as nitrate, sulphate, and phosphate.
If anyone is watching different videos of this test on youtube, I want to tell them that this is the best video among all videos on youtube
Thanku so much sir explain brilliantly 🙂🙂🙂
Thank u sir 🔥🔥🔥very informative
Sir,
I thank you very much for the vedio, i have some doubt where did you find the preparing reagents procedures. bcoz i am seeing diffrent chemicals used for preparing reagents.
Awsm....❤️
how calm, i went to sleep while watching it with background music on🤣😍
Here how many polytechnic.. students are???.raise your hand..
very good explaination!!
Thank u sir ur way of speaking is very good. I can easily understand but m so week in lab works
Same here
Well explained though, thanks for posting this
I have my exams day after tomorros and this video is definately gonna save me. thankyou
This video helped me a lot!
Thank you, it's helpful 😊
thanks for well teaching sir
Video dekhne ke Baad bahot neend aa Rahi hai....that background music!
Does pH affect water hardness? for instance, changing from 7.5 to 6 or 9.
Very good and clear
Thank you so much for this
Thanks for the explanation!!
Is there any video about gross alpha and beta radiationa analysis in water? Thanks
excellent explanation
thank you !! worth watching :)
thanq sir
aaj pahli bar chemistry me pura experiment samajh aaya hai
Thanks sir good teaching tric
all clear thanks sir all tho it was slow but satisfy explanation
Sir, Please do not pippetout AMMONIA BUFFER and transfer the sample in to conical flask by using pippete and not measuring jar..Hope you oblize. .he presentaion is very excellent. suggetion by the SENIOR ANALYST in Govt of AP.
what is generally higher in domestic water temporary hardness or permanent hardness
Thanks sir for good video
thanks sir excellent
Tnq sir it was really helpful

Allan Jay Martirez
Okayy
Just chemistry things 😂
Sir, I have doubt is this test require fresh sample or we can use any sample like 1 week old?
nice explination sir
Thanks well explained
Pleas, upload a video on o henary method for estimation of hardness of water.
does this also work for sea water?
Color test of water plz make a video on this topic
Awesome
Thank you sir
thank you
What if the colour of solution is not turning to blue i.e. remaining same...plz tell what is wrong i am doing..?
Background music 👍👍
you do nice sir
My volume cannot be heard, it is very low volume. Is he saying, BOILING?
Nice Video
I don't actually get the part of adding distilled water to sample water.Yes both of them the temporary hardness has been removed.Instead he would have added additional boiled sample water instead of distilled water.
it is very usefull
This is better than watching Indian Idol on TV
The music is interfering with a rather great explanation video !
The song is any movie soundtrack from 60s-90s in my country. God, ASMR ASMR ASMR
OMG DID HE JUST... Once my prof. told me that she had used her mouth to pipette but damn...
Thanks sir ❤
appreciable ... thank you so much
Bg music se Esa lgta h Mahabharat chl rhi h 🤣
Why do we add ammonia buffer solution
Informative
What is the molarity of EDTA solution
I got all that i learn at school and thank you
at 8:10 you said colour changes to dark rep but it seems blue or violet type

do you have procedure for how to determine calcium hardness
رحم الله والديك
What is the normality of EDTA used pls reply
Hardiness of water solution?
sir more testing parameters water anylysis send plese with reagent preparation thnku .
Video was good ...bt it made me sleep as the speed was too slow and also the background music was making the sound distraction
Very well teaching,thank you
That background music 😂
Aaja water analysis
😂😂
🤣🤣🤣
🤣
What is the name of that bg music..I want it on my death ceremony..🤣😂😂🤣
Music kyo add Kiya h vedio m
Chacha vintage homeopathic dawa ka bottle rakhe hue hai bachpan ka yaad dila diye chacha mujhe
Sir ye bhi nahi pata ki pepatte out bulk pipatte se kiya jata hai muh se nahi
Thank you sir!
Old is gold
Thank you sir.
