A mixture of sugar and sulphur can be separated by
- A) dissolution in water, evaporation and filtration
- B) filtration, evaporation and dissolution in water
- C) dissolution in water, filtration and evaporation
- D) evaporation, dissolution in water and filtration
Correct Answer: C) dissolution in water, filtration and evaporation
Explanation
This Chemistry question is asking how to separate a mixture of sugar and sulphur. The question gives four options, and we are to select the correct one.
To separate a mixture of sugar and sulphur, we need to use a separation technique that will separate the two substances. The correct option is option C, which involves dissolving the mixture in water, filtering it to remove the sulphur, and then evaporating the water to obtain the sugar.
This technique is known as filtration, and it is used to separate a solid from a liquid. The liquid that passes through the filter paper is called the filtrate, while the solid that remains on the filter paper is called the residue.
After the mixture is filtered, we obtain the sulphur residue on the filter paper, and the sugar is present in the filtrate. We can then remove the water from the filtrate by evaporating it, leaving behind the sugar.
It is important to note that this technique only works if sugar is soluble in water, which it is. If sugar was not soluble in water, this technique would not work.
In summary, to separate a mixture of sugar and sulphur, we can dissolve the mixture in water, filter it to remove the sulphur residue, and then evaporate the water to obtain the sugar.
