A coin is not a solid solution as it is typically made of multiple solid components mixed together. A solid solution is a homogenous mixture of two or more substances at the atomic or molecular level. In the case of a coin, the combination of metals like copper, zinc, and nickel would not form a solid solution.
No, a coin made from a combination of nickel and copper is not a solution. A solution is a homogeneous mixture of two or more substances where the components are evenly distributed at a molecular level. In the case of a coin, nickel and copper are simply alloyed together to form a solid material with distinct properties.
If a copper coin is kept immersed in a solution of silver nitrate, a chemical reaction would occur where silver replaces copper in the solution, forming copper nitrate and silver metal. The word equation for this reaction would be: Copper (solid) + Silver nitrate (solution) → Copper nitrate (solution) + Silver (solid)
A saturated solution
No, solid compounds do not have a pH. pH is a measure of the acidity or basicity of a solution, not a solid compound. The pH of a solution can be affected by the solid compound dissolving in the solution.
Yes, copper is a solid solution of copper atoms in a copper matrix. It forms a solid solution when other elements, such as silver or nickel, are alloyed with copper as well.
