What specific biological material did Jean-Antoine Nollet utilize in 1748 to demonstrate the phenomenon of osmosis?
Answer
Pig's bladder
In 1748, Jean-Antoine Nollet conducted foundational research on osmosis by employing a pig's bladder as a semi-permeable membrane. This experiment demonstrated that solvent molecules could move selectively from a solution with lower solute concentration to one with higher concentration, driven by natural osmotic pressure. This early demonstration provided the essential scientific observations that would later underpin the development of pressure-driven membrane technology.
