Answer 2

Explanation:

In chemistry, the word is most often applied to a heterogeneous mixture. This is one which has a non-uniform composition. A mixture of sand and water is heterogeneous. Concrete is heterogeneous. In contrast, a homogeneous mixture has a uniform composition. An example is a mixture of sugar dissolved in water. Whether a mixture is heterogeneous or homogeneous is largely dependent on the scale or sample size. For example, if you look at a container of sand, it may appear to have evenly distributed particles (be homogeneous).

a) iodised salt is heterogenous
