Assertion :In froth floatation process, sodium ethyl xanthate is used as collector.
Reason :Sulphide ores are water soluble.

  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Assertion is incorrect and Reason is correct
Correct Answer: Option(c)
Solution: Froth floatation process used for the concentration of sulphide ore uses sodium ethly xanthate, as collector.
Other examples of collector include ethyl xanthate and potassium ethyl xanthate. They attach themselves to the grains of mineral by polar groups so that minerals become water repellent and pass on into the froth.

Thus Assertion is correct but Reason is incorrect.
