bruh why didn't they finish the experiment, my science assignment is asking for a conclusion but there is none XD
can u plez upload the video for determining CEC using methylene blue
i want to see the end point of titration.
titrate the distillate with 0.2N H2SO4. the color change is from green to purple at the endpoint.
For those solutions the solvent that you are using is water? Thank you for your demonstration.
thank you. it would be good if you completed the whole experiment.
Lookup Colorimetric injection method with a flow injection analysis to complete the knowledge acquisition
Guys any one here doing Tony's Assignment??
In this test method which standard you are using
"So that sample will now go for analysis of ammonium" after watching a school level presentation for 9 minute 30
right? Have you found a better video on CEC testing? I can't find one.
super demonstration!
Why is she not using gloves?
Did she uploaded the colorimetric method video ?
Very interesting. Thanks.
I think I`m in love. :(
what is the reference?
Nice explanation
How to complete test
Thank you
calculations please
Insightful
thanks
THANK YOU!!!!
