Question

To separate colloidal particles centrifugation is used.

• A. True
• B. False

Answer 1

The correct option is A True

Step 1 Understanding the concept:

• A colloid is a type of solution in which the size of the solute particles lies between true solutions and suspensions.
• For example, soap solutions, milk, ink, blood, and synthetic detergent solutions. However a colloid appears to be homogenous, but it is heterogeneous.
• A colloid's particles are larger than those found in a true solution but smaller than those found in a suspension.
• It has a diameter of 1 nm to 100 nm. Even with a microscope, most colloid particles are invisible.

Step 2 Separation:

• Centrifugation is a separation technique that uses centrifugal force to separate two liquids in a mixture.
• The denser component of the mixture migrates away from the axis while the lighter component migrates towards the axis throughout this process.
• The dispersed phase and the dispersion medium are the two parts of a colloidal solution.
• To remove colloidal particles from a colloidal solution, a special technique known as centrifugation can be used. Based on particle size and density, centrifugation has been employed to separate colloids from aqueous solution.
• Thus to separate colloidal particles, centrifugation is used is a true statement.
