28) (1) Name the separation technique you would follow to separate the
mixtures. (a) Clear water from muddy water (b) Kerosene and water (c) Iron
tilings and sand (11) What is the advantage of fractional distillation
distillation ?
(a) decantation and filtration
(b) separating funnel
(c) magnetic separation
Answers
Answer:
1. (a) Clean water can be separated from muddy water by the process called filtration. Filtration is a process that removes particles from suspension in water.
(b) Water and kerosene oil are two immiscible liquids.ao, a mixture of kerosene oil and water can be separated by using a seperating funnel. when the mixture of water and kerosene oil is put in a seperating funnel, it forms two layers.
(c) Wrap a magnet in plastic lunch wrap and move it through the mixture of the three solids. The iron filings will stick to the magnet. The filings can be removed by unwrapping the plastic from the magnet carefully! Mix the remaining salt and sand in water and stir.
(11)Fractional distillation achieves a greater degree of separation between products by taking advantage of multiple vaporisation and condensation processes in the column. So, purity and separation of products are the main advantages.
Hope it helped you...
Please mark it the brain list answer.
One more thing you have already provided the method.. so I have given you the full technique.
