Rate of leaching increases with increasing______________________?
Correct answer: A. Temperature
- A. Temperature
- B. Viscosity of solvent
- C. Pressure
- D. Size of the solid
Explanation
Higher temperature generally increases solvent diffusivity and reduces viscosity, accelerating penetration of solvent into the solid and dissolution of the soluble material. Higher viscosity and larger particle size usually hinder leaching.
