Determination of hardness of Water 

All the best ever RU-vid channel more more subscribers

I'm over joy of your presentation and clear English. Thanks you. I'm studying environmental engineering. I will always follow you sir.

When was this video shot? Has such a soothing 90s vibe to it. Also, very explanatory and simple.

watch it at speed 1.5 u will thank me later

Excellent illustration! Thanks for this guide, it shall come in handy for tomorrow's midterm :)

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?

Even u watch at 2X speed...the vdo still seems to be slow😉

Gorgeous explanation and content thank sir upload more lecture

Thanks for this video 👏😴 Kal Practical hai mera.. saal bhar gya nahi Lab mein aur aaj ye mil gya Dhanyawad ❤

observations table starts from 13:39 Calculations 14:45.

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

I wished you could explain the nutrient in water too, such as nitrate, sulphate, and phosphate.

I have never laughed so much! and the music....:)))

Thank u sir ur way of speaking is very good. I can easily understand but m so week in lab works

You teach really very well sir 🙂

how calm, i went to sleep while watching it with background music on🤣😍

Thank You sir, Explained Wonderfully (y)

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

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.

Bg music se Esa lgta h Mahabharat chl rhi h 🤣

Video dekhne ke Baad bahot neend aa Rahi hai....that background music!

Is there any video about gross alpha and beta radiationa analysis in water? Thanks

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 have my exams day after tomorros and this video is definately gonna save me. thankyou

The music is interfering with a rather great explanation video !

My volume cannot be heard, it is very low volume. Is he saying, BOILING?

Background music name please I want it on my death ceremony

thanq sir aaj pahli bar chemistry me pura experiment samajh aaya hai

What's the use of the loud music in this experiment 😢

Awsm....❤️

It is easy to understand .thank you sir

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.

at 8:10 you said colour changes to dark rep but it seems blue or violet type

what is that background music, so depressing😭😴

Watch it at speed of 2x it will help u to save your time....😀🔥

Color test of water plz make a video on this topic

Very nyc teaching Will you thank u sir

Sir, I have doubt is this test require fresh sample or we can use any sample like 1 week old?

Here how many polytechnic.. students are???.raise your hand..

Chacha vintage homeopathic dawa ka bottle rakhe hue hai bachpan ka yaad dila diye chacha mujhe

good and clean explanation sir ,thank you.

Pleas, upload a video on o henary method for estimation of hardness of water.

The song is any movie soundtrack from 60s-90s in my country. God, ASMR ASMR ASMR

Thank u sir 🔥🔥🔥very informative

background music is too much irritating plz avoid dubbing/putting background music..

This is better than watching Indian Idol on TV

Well explained though, thanks for posting this

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.

very good explaination!!

Sir when we r adding distilled water to the boiled water then there will be some temporary hardness of that distilled water which in turn produces some temporary hardness in the water. Then how can we proceed the reaction further. Please clarify my doubt as soon as possible.

I got all that i learn at school and thank you

Sir ye bhi nahi pata ki pepatte out bulk pipatte se kiya jata hai muh se nahi

Why do we add ammonia buffer solution

Background music 👍👍

Thanku so much sir explain brilliantly 🙂🙂🙂

Thanks well explained

thanks for this video.. this helps me for practical exam

That background music 😂

What if the colour of solution is not turning to blue i.e. remaining same...plz tell what is wrong i am doing..?

what is generally higher in domestic water temporary hardness or permanent hardness

Video was good ...bt it made me sleep as the speed was too slow and also the background music was making the sound distraction

How to prepare EDTA solution

Very good and clear

What is the normality of EDTA used pls reply

Music kyo add Kiya h vedio m

Nice Video

Intiaol buret riding 1.9 kyo aya sir

Sir how to reduce hardness in water

What is the molarity of EDTA solution

Does pH affect water hardness? for instance, changing from 7.5 to 6 or 9.

Awesome

Kya movie chalu he Kya😂😂😂that music...

This video helped me a lot!

does this also work for sea water?

sir more testing parameters water anylysis send plese with reagent preparation thnku .

Sir poison deactivate process

Thankyou sir but Music is so disturbing

Thanks for the explanation!!

Old is gold

do you have procedure for how to determine calcium hardness

all clear thanks sir all tho it was slow but satisfy explanation

Thanks sir for good video

Thanks sir good teaching tric

I have exam tomorrow and I think I can't finish this video today

will u speak so slowly and softly

ഫുൾ സപ്പോർട്ട്

Atrocious laboratory safety and safety techniques. Also notice how the guy operates the burette stopper? I wouldn't recommend the video for learning students.

If you don't mind sir any one mannual in this experiment

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

thanks for well teaching sir

Informative

Mention reference used

Thank you sir.

Tnq sir it was really helpful

Voice is very low

thank you !! worth watching :)

thank u so much sir

Thank you sir
