The thermogram in Figure below shows the change in mass of a sample of Copper sulfate pentahydrate, CuSO++5H2O (249.5 g/mole) as a function of temperature. The original sample weighing 25.0 mg was heated from room temperature to 1000°C at a rate of 5º C per minute. The following changes in mass and corresponding temperature ranges were observed : Loss of 1.80 mg from 100 – 250° C. Loss of 7.212 mg from 350 – 550° C., Loss of 8.015 mg from 600 – 800° C.

![The thermagram in Figure below shows the change in mass of a sample of Copper sulfate
pentahydrate, CuSO++5H2O (249.5 g/mole) as a function of temperature. The original sample
weighing 25.0 mg was heated from room temperature to 1000°C at a rate of 5º C per minute.
The following changes in mass and corresponding temperature ranges were observed :
Loss of 1.80 mg from 100 – 250° C.
Loss of 7.212 mg from 350 – 550° C.,
Loss of 8.015 mg from 600 – 800° C. Determine the identities of the volatilization products and
the solid residue at each step of the thermal decomposition.
Given that: H=1 g/mol , S =32 g/mol , 0=16 g/mol.
