Which of the following are mixtures?

i. Petroleum ii. Rubber latex. iii. Vulcanizer’s solution iv. Carbon (II) sulphide

A. i, ii and iii

B. i, ii and iv

C. i and ii only

D. i and iv

QUICK ANSWER…

A

SOLUTION…  

A mixture is any heterogenous substance whose components can simply be separated by physical means. It is different from a compound which is homogenous and whose component atoms are held together by a chemical bond. Let’s analyze each of the substances to ascertain which is a mixture:

  • Petroleum: petroleum is a good example of a mixture, this is because it contains individual components such as kerosene, diesel, natural gas, petrol, bitumen, coal tar, and so on… These can simply be separated by physical means (fractional distillation).
  • Rubber latex is also a mixture, this is because it is the white sap that comes from the rubber tree which contains water, proteins, carbohydrates, lipids, and other components.
  • Vulcanizer’s solution is another example of a mixture which comprises phosphorus, sulphur, benzene, and rubber.
  • Carbon (ii) sulphide is a homogenous compound whose atoms are chemically bonded together. It not a mixture but a compound.

Now for the right answer to the above question:

  1. Option A is correct.
  2. Option B is incorrect. carbon (ii) sulphide is a homogenous compound and not a mixture.
  3. C is incorrect. vulcanizer’s solution is also a mixture.
  4. D is not the correct answer. carbon (ii) sulphide is a homogenous compound and not a mixture.

QUICK TIPS…

You may please note these/this:

  • Mixtures comprise components which are not chemically bonded together and which maintain their individual properties within the mixture.
