Question

Give one example of the following:

Solution of a solid in a solid

Answer 1

Example of a solid in a solid solution is Brass. Brass is a mixture of Copper $\left(\mathrm{Cu}\right)$ and Zinc $\left(\mathrm{Zn}\right)$

• Other examples are Bronze-mixture of Copper $\left(\mathrm{Cu}\right)$ and Tin $\left(\mathrm{Sn}\right)$, Steel- mixture of Iron $\left(\mathrm{Fe}\right)$ and Carbon $\left(\mathrm{C}\right)$ etc.
• Solid in solid solutions are called alloys
• Alloy: An alloy is a homogeneous mixture of two or more elements in a physically combined state.
• They are called solid solutions because in this, elements act as solvent (the substance present in a larger quantity in a solution) and solute (the substance present in a smaller quantity in a solution)

Solution: A solution is a homogeneous mixture of two or more components. Example: alloys, salt solution etc.

Homogeneous mixture: A mixture that has a uniform composition and properties throughout its mass is known as a homogeneous mixture. Example: alloys, salt solution etc.
