The correct answer is option A.
All the particles carry the same charge, which could be either positive or negative.
All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.
For example, soap solution (sodium palmitate) dissociates into ions:
C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺
The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.

Answer: 10.9 mol.
Explanation:
- To understand how to solve this problem, we must mention the reaction equation where water produced from PbO₂.
Pb + PbO₂ + 2H₂SO₄ → 2PbSO₄ + 2H₂O
- Now, it is a stichiometric oriented problem, that 1 mole of PbO₂ produces 2 moles of H₂O.
Using cross multiplication:
1.0 mole of PbO₂ → 2.0 moles of H₂O
5.43 moles of PbO₂ → ??? moles of water
The moles of water produced = (5.43 x 2.0) = 10.86 moles ≅ 10.9 moles.
