Numerical # 1 : A laboratory procedure calls for 250 mL of an approximately 0.10 M solution of NH3. Describe how you would prepare this solution using a stock solution of concentrated NH3 (14.8 M).
Q2
: As an example, say you need to prepare 50 milliliters of a 1.0 M solution from a 2.0 M stock solution. Your first step is to calculate the volume of stock solution that is required
Q 3:
You wish to prepare a calibration curve for the spectrophotometric determination of permanganate. You have a stock 0.100 M solution of KMnO4 and a series of 100 ml volumetric flasks. What volumes of stock solution will you have to pipet into the flask to prepare standard of 1.00 × 10-3 M, 2.00 × 10-3 M, 5.00 × 10-3 M and 10.0 × 10-3 M KMnO4 Solutions?
Q4:
Suppose that in one of your general chemistry experiments, you are required to use 2 M sulfuric acid (H2SO4) for a certain reaction, but your lab instructor gave you 5 M H2SO4. How would you go about this?
your method of teaching is very amazing seriously i understand everything very well Even i hated chemistry but after watching this video i started to love chemistry
Thank you so much for such an appreciating & encouraging comments, that comments are source of motivation for me and provide me energy to work more
Amazing, zabrdst akheer ho gai sir g mzza a gya👍👍👍👍👍👍☑️☑️☑️☑️☑️☑️☑️☑️

Sir amazing vedio excellent 👍
Sir what is difference between M1V1M2V2 & C1V1C2V2 Can be used both for same situation ? Plz guide kr dein
Teaching is the best sir 🙏
Shital thank you so much for your comment
I m really glad to see your comments 🌺🌹🌸
@@chemistrybysaadanwar wc sir 🙏
Very easily explained by u sir
Sir kindly make essential oil stock solution and its working solutions of 2, 3, 5, 7,10 percent concentration
Sir I'm facing problem regarding, if we find the stock solution whose volune is 1 ml then how will we write it down on paper that we have this solution in .......amount..?
Thank you so much sir
Your welcome
Thank u sir.
Amazing
Verry good demonstration 👍👍👍👍👍👍👍
Thank you so much for your comment
Stay blessed
zabrdas tareqe se samjaya ha sir
Thank you
I want to stocks concept mazer stock, macrostocks.. Like this
Thank you so much for your encouraging words & feedback comments
It was much needed sir thanks for this lecture
Your welcome
@@chemistrybysaadanwar how to make concentration solution? Can u give a 1-2 liner answer to this ques?
Sir, i am Undergraduate but today because of your lecture i understand that how to make solutions😂
Thank u so much sir
You're welcome 😅😀
If possible please share the link of these educational videos with your classmates & friends & thank you so much for your encouraging words & feedback comments
@@chemistrybysaadanwar Ok sir i'll definitely do it

Sir please "introduction to analytical chemistry "multiple choice questions. Please sir!
Yeah sure inshallah zaroor
Yeah sure inshallah zaroor
Ok! Thanks sir 😇
Sir,
I have to mix carbon=1 gm
And dichloromethane methane in different concentrations (which is in liquid form in bottle)=50 mg/L, ,40mg/L, 30mg/L
Please tell me how to make these solutions with these different concentrations.
Anjali 🙏
@@chemistrybysaadanwar sir,
Please reply the question I asked above...
Sir we have already 250 ml in statement then why u have written the answer in liters and then convert in milliters .
At which point?
I have uploaded it many month ago and now I don't remember each & every thing clearly I have to watch the lecture again
Probebly I was not correct at that point if we already had in ml then no need to convert again into ml
@@chemistrybysaadanwar In numerical#1
@@chemistrybysaadanwar Thanks Sir for replying.
You are doing great job .
