An impure sample of CaC2O4H2O is analysed using TGA technique. TG curve of the sample indicates the total mass change from 85 mg to 30.7 mg when this sample was heated upto 1173 K. calculate the purity of the sample
In this case, Thermal Gravimetric Analysis (TGA) is being used to analyze the impure sample of CaC2O4H2O. TGA is a technique used to determine the mass of a sample as it is heated, providing information about the sample's thermal stability and composition. The TG curve provides insights into the change in the sample's mass as a function of temperature. Here, the total mass of the sample changes from 85 mg to 30.7 mg when heated up to 1173 K.
To calculate the purity of the sample, we need to understand the thermal decomposition process of CaC2O4H2O. On heating, CaC2O4H2O decomposes to form CaCO3, CO2,
