Why it is the gemstones is one example of solid sol?

Answer 1

Solid sol is a kind of solid that is a little soft. If you have a Coloured gemstone

just take it and put it in a boiling water after 5-6mins take and press it you may feel a bit change in it. It becomes kind of soft. This is how we get to know that coloured gemstones are solid sol. However this property isn't there for perfect solids.

Answer 2

Gemstones are an example of solid solutions because they are composed of different elements or compounds that are homogeneously mixed in a solid state. This results in a uniform distribution of components within the crystal lattice structure of the gemstone, creating a single solid phase with distinct properties.

Answer 3

Gemstones are often considered examples of solid solutions, particularly when they involve variations in the composition of minerals within the crystal structure. A solid solution is a type of homogeneous mixture where different elements or compounds are incorporated into the crystalline structure of a solid material. In the case of gemstones, this is commonly seen in minerals that form crystals.

For example, the mineral corundum can crystallize in different forms, giving rise to gemstones such as sapphires and rubies. Corundum is primarily composed of aluminum oxide (Al2O3). However, during the crystal formation, small amounts of other elements can substitute for aluminum or oxygen in the crystal lattice. For instance, in blue sapphires, iron and titanium impurities can replace some aluminum ions in the crystal structure, leading to the blue coloration. Similarly, the presence of chromium can result in the red color of rubies.

This variability in composition within the crystal lattice is an example of a solid solution. The impurities or substitution of elements create variations in the physical and optical properties of the gemstone. Solid solutions can also impact the color, hardness, and other characteristics of gemstones, making them unique and valuable.

It's worth noting that while gemstones are a common example of solid solutions in minerals, solid solutions can also be found in various other materials, including alloys, ceramics, and polymers.
