Question

Which among the following is a heterogeneous mixture?
1) 22 Carat gold
2) Rectified Spirit
3)Gasoline
4)lodised tableSalt

Answer 1

Answer:

1 is the answer because 22 carat gold has some impurities

Answer 2

Answer:

While a heterogeneous mixture comprises components in at least two separate phases, a homogeneous mixture has a non-uniform composition with all of its components present in a single phase.

Explanation:

Due to the consistent consistency of each fuel (which is the same throughout the sample area), gasoline is a homogenous mixture. When a combination is mixed well enough to seem uniform throughout, it is referred to as a homogenous mixture.

22-carat gold is a mixture of 22 parts of gold mixed with two other metals such as zinc, and copper. It is a completely fine mixture, so it can be regarded as a homogeneous mixture.

Rectified spirit is a mixture of 95.5% ethanol with a 4.5% water mixture. It is not mixed thoroughly so it is a heterogeneous mixture.

It is a homogenous mixture, of table salt. Physically mixed to make it impossible to distinguish between the components, it contains more than one material. It comprises many substances, hence it is not a compound.

Hence, the correct option is (2) Rectified spirit.
