What is hydration? On which factors the rate of hydration depends?

Definition of Hydration:

• Hydration refers to the process by which a substance absorbs water.

Factors Affecting the Rate of Hydration:

1. Temperature:
   • Higher temperatures generally increase the rate of hydration.
2. Surface Area:
   • Greater surface area of a substance results in a faster hydration process.
3. Nature of Substance:
   • Chemical and physical properties of the substance can influence how quickly it hydrates.
4. Concentration:
   • The concentration of the water and the substance can impact the hydration rate.
5. Presence of Catalysts or Inhibitors:
   • Certain chemicals can either speed up or slow down the hydration process.
