CH.3 (Mixtures) 22 to 26

We can use solvent extraction method for solid-solid mixture when.

• One component is soluble and the other component is insoluble
• One component is less soluble and the other component is more soluble
• One component is magnetic and the other component is non-magnetic
• One component is sublimable and the other component is non-sublimable

We can use fractional crystallisation for solid-soild mixture when.

• a) Both the components are soluble
• b) One component is less soluble and the other component is more soluble
• c) One component is magnetic and the other component is non-magnetic
• d)One component is sublimable and the other component is non-sublimable
