Paragraph: The most important property of hydrophobic colloidal...
Paragraph:
The most important property of hydrophobic colloidal dispersions is that the particles carry electric charge. This charge is largely responsible for the stability of lyophobic solsParagraph:
Which of the given statement(s) is/are correct?
Options
- AThe particles of a colloid carry similar charges
- BThe repulsive forces between charged particles provide stability to the colloidal solution
- CThe particles of a colloid carry equal and opposite charges
- DThe attractive forces between these charged particles provide stability to the sol by lowering potential energy
Correct answer
B. The repulsive forces between charged particles provide stability to the colloidal solution
Step-by-step solution
The particles of sol carry equal and similar charge which causes repulsion among particles thus preventing coagulation
