Solid-solid homogeneous mixture give one example

Example of solid - solid homogeneous mixture is copper metal - silver metal like coins and alloys. Homogeneous mixture is a mixture in which one of the substances often changes in form as in a solution of sugar in water. It contains variable proportions. Solution can contain two substances, three substances or more, in a single physical state. The component of a solution that is present in greatest quantity is usually called the solvent and all other components are called solutes.

An example of this type of mixture is steel, which is a mixture of carbon and iron metal. These types of homogeneous mixtures involving metals are often referrers to as alloys.
