* Describe what quantity is measured and how the measurement is performed for each of the following
techniques: (a) TGA, (b) DTA, (c) DSC,
V A 0.5927-g sample was dissolved, and the Ca2" and Ba2t ions present were precipitated as BaC,O,
„H,O and CaC,O, H,O. The oxalates were then heated in a thermogravimetric apparatus leaving a
residue that weighed 0.5127 g in the range of 320°C-400°C and 0.4362 g in the range of 580°C-620°C.
Calculate the percentage Ca and percentage Ba in the sample.

v Describe any one thermal analysis technique other then the described ome in this lectures. You can
try to invent a new technique. But it should be therpnal property depended.
