I am not sure what is heat to constant mass analysis because i have not learned it yet and though question specifically says 'using gravimetric anaylsis' so I am confused.Kushal said:I don't think fractional distillation would be called gravimetric analysis. You should go for a heat to constant mass analysis.
It expands and evaporates due a low boiling point, right?Kushal said:What do you know about mercury oxide when heated?

Gravimetric analysis is a quantitative analytical method used to determine the amount of a substance present in a sample by measuring its mass. It involves isolating and weighing the substance of interest, often through precipitation or volatilization methods.
To analyze mercury oxide using gravimetric analysis, the sample is first heated to convert all of the mercury to its oxide form. The oxide is then isolated through filtration and heated to convert it back to pure mercury. The difference in mass before and after the reaction is used to calculate the amount of mercury oxide present in the sample.
The main sources of error in gravimetric analysis of mercury oxide include incomplete conversion of the sample to its oxide form, loss of the precipitate during filtration, and contamination by other substances during the analysis process. It is important to carefully control and monitor these factors to ensure accurate results.
Due to the toxicity of mercury, it is important to take proper precautions when working with mercury oxide in gravimetric analysis. This includes wearing appropriate personal protective equipment, working in a well-ventilated area, and properly disposing of all materials after the analysis is complete.
Gravimetric analysis has several advantages over other analytical methods. It is a highly accurate and precise method, as the results are based on the measurement of mass rather than volume or concentration. It is also a relatively simple and inexpensive method, making it suitable for routine analysis in laboratories.
