1. (a) What are the requirements that should be met for a precipitation reaction to serve as the basis of a gravimetric method? (b) What is "digestion"? In what ways can digestion improve the quality of an analytical precipitate? (c) A typical thermogravimetric curve for magnesium oxalate (MgC:O.) precipitates is given below. 18 134 226 398 478 900 Temperature, C Describe the weight loss as a function of temperature. Select a suitable ignition temperature for the gravimetric analysis of magnesium. Explain your choice. i. Predict the possible composition of the residues collected at the chosen temperature, i.
