Particles of substance x are dispersed in water to form a colloid. which describes the electrical charges on the particles of substance x? all the particles carry the same charge, which could be either positive or negative. each particle carries a charge that is slightly different from the other particles. half of the particles carry a positive charge; the other half carry a negative charge. all the particles are uncharged, or electrically neutral.

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.
