Determination of an Acid (Monoprotic) by Titration Lab

Click For Summary
SUMMARY

The discussion centers on the challenges of identifying an unknown monoprotic acid with a molar mass of 209.70 g/mol through titration. The participant found similar compounds, such as H4O7V2 and HCl2I, but emphasized the limitations of relying solely on molar mass for identification. They noted that without additional data, such as melting point or qualitative tests, determining the acid's identity is impractical. The conversation highlights the necessity of supplementary information for accurate identification in titration labs.

PREREQUISITES
  • Understanding of monoprotic acids and their properties
  • Familiarity with titration techniques and calculations
  • Knowledge of molar mass determination and its significance
  • Experience with qualitative analysis methods in chemistry
NEXT STEPS

Please post this type of questions in HW section using the template.
I tried looking for my unknown (209.70 g/mol) online and couldn't find it. The closest I found were H4O7V2(217.907 g/mol) and HCl2I(198.819 g/mol), but I know I am correct to a 2.7% accuracy. What other lists can I use to solve this?

Plenty of organics that could fit. But i you will use some kind of database you can expect hundreds of hits, so it won't help much. If you are not given a short list to choose from or if you have no other information trying to determine the acid identity just from the molar mass is a waste of time.

Grant,
Do you have more given information to use? Maybe melting point of the sample, or some other qualitative tests? Is your unknown acid supposed to be inorganic, or organic? Have you just ONE acid in the sample, or more than one?
