Limitations of procedures in experiments
I was wondering what exactly is meant by "limitations" here. I understand that conclusions can be limited in their accuracy by the accuracy of the data they're based on but I'm not sure what I should be including for limitations of the procedures. The main procedures in my experiment were titrations and standard solutions.

I searched some threads asking a similar thing in the past but they mainly seem to suggest things like uncertainty and making sure you read the scale from the bottom of the meniscus but I don't think that's the sort of thing it means.

Basically what is meant by "limitations" in this context?

Thanks in advance!

Limitations just means to what extent the procedures can be applied and how accurate they are.

Titrations can only be used if the actual object of analysis reacts with something appropriately and is indicable. However, in reality there are many ingenious ways to apply titration for analysis (back titration, conductimetric etc)

Another issue is the concentration. It must be within certain limits. This isn't a problem for solutions that are too concentrated as they can be diluted before analysis, but for very weak solutions it can be a problem.

In terms of precision, you should appreciate that the inherent apparatus and procedure limits the degree of accuracy. How close can you get to the 'right' answer? How reproducible (precise) is the methodology?
