This text describes the results of several experiments conducted by an alchemist in the 17th century.
The alchemist dissolved a substance in water and then evaporated the water, leaving behind a black residue.
The alchemist then heated the residue, which produced a white sublimate.
The alchemist also heated the sublimate, which caused it to fume away.
Here are some questions about the experiments:
- What was the substance that the alchemist dissolved in water?
- What was the black residue that was left behind after the water evaporated?
- What was the white sublimate that was produced when the residue was heated?
- What happened when the sublimate was heated again?
Here are the answers to the questions:
- The substance that the alchemist dissolved in water was likely a metal or mineral.
- The black residue that was left behind after the water evaporated was likely the metal or mineral oxide.
- The white sublimate that was produced when the residue was heated was likely the metal or mineral chloride.
- When the sublimate was heated again, it fumed away, which means that it vaporized and then condensed into a gas.
