So, yes, and Instrument limit to two decimal points as well as once we reach the cmc (here, 125 ppm), errors were expected that low.

Yes. I would say yes, all the questions you asked have been checked by us already. We have checked low ppm to high ppm, all 60 measurements have the same interval. 175 ppm is just for reference that I used here for how to find uncertainty for the unmeasured point. Is there any way I can use all...

You can refer to this image.

I do not see any pattern here but usually, in an interfacial tension graph, it starts with decreasing and then remains stable.

So, the last column (error) obtained from the instrument (it is automatically calculated by the standard deviation of 60 measurements) I want to find out/predict the exact point where the value becomes stable or consistent (by observing a horizontal straight line.

Here I attached the measurements and errors for the measured values but I have not measured at the 175 ppm. so, how one may find errors for the unmeasured point?

Can't I predict from the other measured points?

So now, can I find the uncertainties or errors of where two straight lines (trendlines) touch (around 90 ppm)? Thank you.

I have attached the graphs here for the same data. I can use the data both ways using tread lines.

Hello expert, I understand what you are trying to say. Let me explain. So, In this graph, I have taken my measurements at different concentrations. So, I have taken at 25 ppm to 400 ppm. I have the value and the error/uncertainty for the exact concentration (i.e...
