Osmosis is the movement of water molecules, across a semipermeable membrane, from a hypotonic solution to a hypertonic solution

Osmosis is critical in the maintenance of the right amount of water in the cells an organism. Water is a universal solvent and is especially important for biochemical activities of a cell. Osmosis maintains the right water homeostasis in cells.

Osmosis is useful in the absorption of water by the roots of the plants and the maintenance of transpirational pull that ensures herbecious plants remain upright.

Osmosis enables the opening and closing of plant stomata hence regulating the loss of water by the plants.

yKpoI14uk [10]

Pb(C₂H₃O₂)₂ is lead(II) acetate

Pb(C₂H₃O₂)₂ --> Pb²⁺ + C₂H₃O₂²⁻

Lead(II) acetate ionizes in aqueous solution to form lead cation and acetate anion.

The chemical formula for the anion present in the aqueous solution of Pb(C₂H₃O₂)₂ is C₂H₃O₂²⁻

C₂H₃O₂²⁻ or CH₃COO⁻ is called the acetate ion.

Therefore, the correct answer is C₂H₃O₂²⁻
