Question

Why do we crush solids before putting them into a solvent?

Answer 1

To increase the surface area of the solute and ensure Maximum interaction with the solvent.

Step-by-step explanation:

It is usual practice that a solid is crushed before adding it to the solvent to form a solution.

It is common knowledge that a crushed solid solute dissolves faster in a solvent than a solid lump. This is because, when the solid is crushed, a greater surface area of solute is exposed for interaction with the solvent compared to a lump solid solute. This increase in surface area leads to more effective dissolution of the crushed solid solute compared to a lump solid solute .

Answer 2

If you didn't crush up the solid, then it would be harder to dissolve.
Crushing the solute (solid) increases the surface area and makes the solute dissolve faster.
