Thermogravimetric analysis (TGA)
Thermal and Atomic Methods (Intro) · Chemistry
Study notes
TGA of CaC₂O₄·H₂O shows mass losses at 200°C, 500°C, 800°C. Interpret. Step 1: 200°C: loses H₂O (hydrate water) → CaC₂O₄. Step 2: 500°C: loses CO → CaCO₃. Step 3: 800°C: loses CO₂ → CaO (stable residue). Step 4: Each plateau = stable compound — TGA reads decomposition story!
