Solids and Concentration

[Talia Leano 2H]

Why don't solids have a concentration?

[Coleman Morrow]

The concentration of a pure liquid or solid is just its density divided by its mass and if it doesn't change on either side of the equation, meaning none of it is dissolving, then there is no point in including it in the k equation.

Why don't solids have a concentration?

Solids aren't considered to have a concentration in terms of calculating equilibrium because they cancel out on both sides of the equation, or they don't have an effect on the equilibrium state of a reaction.

I believe it's because solids have a fixed volume and do not dissolve when put into a solvent. Therefore, the solid concentration remains unchanged and does not affect equilibrium.

Their volume does not change and they do not dissolve in solution

[Dane_Beasley_1E]

Solids do not have concentration because their volume is fixed and they do not dissolve in a solution.

[Sarah Salam 1J]

They don't dissolve or change volume, and so they don't affect equilibrium, so their concentration doesn't matter.

[Thomas Gimeno]

Concentration is the ratio of solute to solvent meaning the amount of something in solution compared to the amount of the solution itself. This doesn't really make sense for a solid because if I just hold some salt for example, there is no solute or solvent. However, Density is a measurement similar to concentration because density is the ratio of the amount of something to the amount of space it takes up.

Why don't solids have a concentration?

Solids have a fixed volume and so not dissolve in solutions. Hope this helped!
