Chem IA - Is Standardisation Necessary?

Recommended Posts

For my IA, I am doing a redox titration using sodium thiosfulate. My question is: if my school has provided me with a jug of sodium thiosulfate labelled 0.1M, would I still need to standardise it for my Chemistry IA? Or can I just assume that figure is correct? I'm afraid if I do this I will lose marks on methodology although I could just mention this in my Evaluation. Help would be much appreciated!

Doing the standardization and showing evidence of it can further your analysis and demonstrate personal engagement, but you won't be penalized if you choose not do it, and can still evaluate it.

You won't lose marks on methodology for not standardizing.

By showing evidence of it do you mean putting pictures of the standardisation in?

That could be one way of doing it, but if you just formally state it, they'll have to take your word for it.
