Question:
The thiourea in a 1.455 g sample of organic material was extracted into a dilute sulfuric acid solution and titrated with 37.31 mL of 0.009372 M Hg²+ via reaction:
4(NH2)2CS + Hg²+ [(NH2)2CS]4 Hg2+
(7) Is this an example of a total analysis technique or concentration technique? Explain.
(8) Calculate the percent (NH₂)2CS (76.12 g/mol) in the sample.
(9) What is a classification of the analysis based on the amount of sample and amount of analytes present? Explain?
(10) If the true value is 10.00%, calculate the absolute and relative error.
