Question

Give one example of the following:

A solution of two solids

Answer 1

Solution: A homogeneous mixture of two or more components mixed together.

• A solution is formed when a solute and a solvent combines.
• Solute: The component of solution which is present in a lesser quantity or a substance that is dissolved.
• Solvent: The component of a solution which is present in a larger amount or a substance in which solute is dissolved.

A solution of two solids means that the solute as well as the solvent is a solid.

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)
