< b="" />Heterogeneous Mixture: 22 Carat Gold, Rectified Spirit, Gasoline, Iodized Table Salt< />

< b="" />Definition of a Heterogeneous Mixture< />
A heterogeneous mixture is a type of mixture that consists of different substances or components that are visibly distinguishable. These components do not mix uniformly, and their distribution is not consistent throughout the mixture.

< b="" />Explanation< />
A mixture is formed when two or more substances are combined physically, without any chemical reaction taking place. In the case of a heterogeneous mixture, the substances that are mixed together do not merge into a single phase and can be observed separately. Let's examine the components mentioned in the question to determine if they form a heterogeneous mixture.

< b="" />22 Carat Gold< />
Gold is a chemical element, and in its purest form, it is a homogeneous substance. However, 22 carat gold is an alloy that contains other metals such as copper and silver. These additional metals create variations in the composition and color, making it a heterogeneous mixture.

< b="" />Rectified Spirit< />
Rectified spirit, also known as rectified alcohol or neutral spirits, is a type of ethanol that has undergone a purification process. It is usually derived from fermented grain or molasses. Since rectified spirit is a pure substance, it does not contribute to the heterogeneity of the mixture.

< b="" />Gasoline< />
Gasoline, commonly used as a fuel for automobiles, is a mixture of various hydrocarbons. These hydrocarbons are obtained from crude oil through a refining process. Gasoline, being a mixture, consists of different components, including benzene, toluene, and octane. Therefore, it can be considered a heterogeneous mixture.

< b="" />Iodized Table Salt< />
Iodized table salt is a common household item used for seasoning food. It is a mixture of sodium chloride (NaCl) and a small amount of iodine. Although it appears homogeneous, the presence of iodine particles dispersed throughout the salt crystals makes it a heterogeneous mixture.

< b="" />Conclusion< />
Based on the analysis of the components mentioned, the mixture of 22 carat gold, rectified spirit, gasoline, and iodized table salt can be classified as a heterogeneous mixture. The varying compositions and visible distinguishability of the components contribute to its heterogeneity.
