When a river meets the ocean they generally form delta due to :
Correct answer: A. Coagulation of sand
- A. Coagulation of sand
- B. sedimentation of common salt
- C. deposition of MgCl2
- D. mutual coagulation
Explanation
Sand is a negatively charged colloidal particles, which is carried by river to the ocean which is a vast reservoir of Na+, Mg+,K+, ion. These cations coagulate sand particles at the meeting point of river and ocean. In this way delta is formed.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
