well explain! from matric to still graduation i was confuse about all thes ppm and ppb but now it very easy for me just bbecase of you thanks alot ma'am you are a good facilitator
Assalam o Alaikum mam .. Its great to see here .... Its my humble request to you to make lectures on caliberation and caliberqtion curves ,standard addition and internal standqrd addition . You r the best ever teacher of analytical chemistry i have ever met in my life .
Really glad to see you respected mam, felt the magic moments of your class during my masters (2009-11). One of the Best Teachers of analytical chemistry. The way you taught was so amazing. Thank you mam for being the most supportive teacher I have ever met and no doubt what I am today is just because of your efforts, concept based teaching methodology and support. In short, I have no words to pay my gratitude.
@@gulrazgullu take any salt of iron. Divide molecular mass by atomic mass and dissolved resultant value into 1 liter solution. It will be 1000 ppm for iron. Now take 10 ml of this solution and make up to 100 ml by dilution. It will be 100 ppm. Now from this 100 take 1, 2, 3, 4 and 5 ml and dilute up to 100. You got 1, 2, 3 ,4 and 5 ppm solution for iron
I think it is too late to reply. However if you dissolve 500mg of NaCI in 10 mL then it is 50000ppm solution. Now from this stock solution you have to apply dilution factor for low grade preparation.
maam you are saying that take 1g of solute and dissolve it in 1000mL of water its will be equal to 1000ppm (1g/L=1000ppm), i am skeptic about this method, because How you can ignore the molecular weight of a given compound during the ppm solution preparation??????????
When we talk about 1ppm solution of a whole compound it mean that that compound is one million part of total solution. Here its weight is not involved.
Mam I have a question! Ham 1000 ppm say 10 ml ppt k ly q ly rhy hian? Or us ko 100 ml main q dissolve kr rhy hain ? 10 ki jagh 2 ml ya 100 ki jagh 50 ml nhii kr skty?
Sorry Beta could not reply you in time. You can reduce amount taken from stock solution and also reduce amount of total solution. I will add a lecture on it soon as it need complete explanation.
Sorry dear for very late reply. If you dissolve 100mg in 1000 mL then it is 100ppm but if you dissolve 100mg in 100mL then it is 1000ppm solution of that compound. If you feel any confusion you can ask.
@@foziabatoolChemistry mam I'm doing a project work on absorption studies using methylene blue dye..which is to be dissolved in distilled water...mam pls tell me the concentration to be used ...how much stock is required and how much dye will go in d.w
@@saloniVerma-mf6yc dear suitable concentration for standard is 1000 ppm by dissolving 1 g in 1 liter solution. Then prepare 30, 60, 90, 120 and 150 ppm working solution for adsorption study.
@@foziabatoolChemistry mam my work is to set the pH ranging from 3-9 and then adding a raw material in each sample...I'm confused how much raw material will be transfer in each sample of 1000ppm
For glucose if you want to prepare different ppm solution, then first prepare 1000 ppm stock solution by dissolving 1000 mg/ 1 g of glucose in 1000mL solution. Then by dilution prepare required concentration
well explain!

Mam your method of teaching is so nice ...very informative video
Very good explanation..... Thank you
NICELY EXPLAINED MAAM/....THANK U SO MUCH
very informative and explanation way is very good
great work mam thank you very much
fantastic Ma'am!🎈👍🎯

Thank you beta for your respect. I am also proud to have student like you. Stay blessed
This is wow! Thank you.
Great mam proud to be ur student
Awesome explanation
V good way of explanation ma'am
great work thanks
Very nice explain.
Good explanation😍
Good energy ma'am keep it up
Mashaa Allah great efforts
Thank you ma'am ❤
Thank u mam very informative
very well explained mam
Excellent lecture.
Subhanallah bhut badiya samjaya mam thq u
👍 mam u r great in clearing concepts
Thanks a lot
Well explained
Very good , well explained, it is a difficult subject but well done , keep it up…
Very nice mam
V vgood thanks
THANKS
Mam plz continuously upload videos
Well explain how to make . 5ppm 1ppm 1.5ppm 2ppm for iron analysis in water

assalam o alikum mam .....mam can u make a video on sample and sampling process
Aoa mam I am ur student Nasr Iqbal . It is ur great effort. Plz mam chromatography mery kafi weak h .make a video on chromatography
Beta it was made in Corona for students. I will try to add on chromatography
Medam hamko spectrophotometer calibration ke liye low range ka (0.1, 0.001, 0.05, 0.01)sio2 solution kaise banayenge pls explain.
❤❤
Mam please make vedeos for percentage solutions and
Normality
Molarity
JazhaKAllah,
ma'am please help me to know -using the stock solution of 500mg/10mL NaCl in Distilled water. So what ppm should I take for dilution?
I think it is too late to reply. However if you dissolve 500mg of NaCI in 10 mL then it is 50000ppm solution. Now from this stock solution you have to apply dilution factor for low grade preparation.
Mam how to prepare ppb solutions from ppm please explain it

Mam if we are taking 100mg in 100ml then what it means
And we have to make sample for uv

500ppm bnana ho toh ?

Plzzzzzzzzzzzzzzzz reply
For glucose if you want to prepare different ppm solution, then first prepare 1000 ppm stock solution by dissolving 1000 mg/ 1 g of glucose in 1000mL solution. Then by dilution prepare required concentration
