Sir,How can prepared sodium chloride?
I understand better sir
Excellent. Very nicely explained 🙏🙏
sir main water company main kaam karti hu complete water testing ki video banaye please
nice
Sir, please make a video on how to make standard hard water by CaCO3 . I am in problem. Here is no video on this topic on you tube.
Pipetting using mouth as an aspirator is not safe 😅
It is n/50 solution, ...... many times i drink this (accidentally while pipetting)😅😅 So its safe ,
Very useful ❤
Normality of AgNO3 solution ?
How do you know strength of std hard water?
It's prepared known solution from laboratory, which will be taken as reference to measure the concentration of unknown solution.
Everything is well but the part of strength of hard water sample in titration 1 calculation. Where is the 0.01 from sir?
Thanks for your doubt.... Calcium carbonate solution is taken as standard solution here. Usually one known concentration solution will be provided to measure the concentration of unknown solution. For each volumetric analysis you will be provided with a standard solution. For this experiment, I had prepared the 0.01 N solution of hard water. So that, I mentioned the same in this video.
@@dpchemistry8122 Satisfied 😌 Thank you sir
Tq so much sir you are very well explained sir
Thank you sir
Thank you sir
very nice explanation
Calculations in different units
How to take volume readings of EDTA sir.. Is it volume consumed or Is it showing reading in burrete
We need to measure the volume consumed of EDTA. For example, 19.5 ml consumed for the titration means, you have to take the same for calculation.
Tamil la Explain Panni irutha nalla irukum sir.enaku purila😢
Will try in future.
@@dpchemistry8122 ok tomorrow University lab atha keta sir.
❤
Very usefull sir 👍
Thank you sir
Do we add water 50 ml on burette in titration 2 and 3 or we should keep the remaining edta solution after titration 1
We should fill the burette with 50 ml of EDTA before starting each titration. There is no need of water.
It's very useful ❤️
Couldn't understand half no English still thank you though
Will improve the language in upcoming videos. Thank you for the feedback
Sir please continue making vedios these are very helpful
Sure @Prashanth Reddy👍
When I added the EBT in water sample, the colour change into blue. What happen ?
Dear Wai myo, Please check the acidity and basicity of water. Due to that also the EBT may show blue color.
Thanks mastaruuu🙏🙏🙏
Thank u sir. Your explanation is so good and easy to understand
Amazing!...👍
Can you give the normality of each solution sir ..
Dear Aswini, Usually we use 0.1 N or 0.01 N solutions for the analysis.
This video very usefull sir
Nice Sir 👍.... We included this topic in more details in material science course.
Very nice sir
Understand easily, thank you sir
You are most welcome
super
Thank you
Its very nice lecture I really lovable
