Final answer:
The incorrect statement is A) Coarse salt dissolves faster in water than fine salt. Fine salt dissolves faster due to its larger surface area, while solubility is an intrinsic property that does not depend on particle size.
Step-by-step explanation:
The incorrect statement regarding the solubility of coarse salt and fine salt is A) Coarse salt dissolves faster in water than fine salt. This statement is incorrect because fine salt has a higher surface area than coarse salt, leading it to dissolve more rapidly. The dissolution of a solute like table salt (NaCl) into a solvent such as water is a surface phenomenon, where solvent molecules collide with the surface of the solute. Fine salt, with its smaller crystal size, exposes more surface area than coarse salt, thus enhancing these collisions and increasing the rate at which the salt dissolves.
The solubility of a substance like salt depends on the nature of the solute and solvent and is quite specific; however, it does not depend on the size of the salt crystals. Statement C) Solubility depends on the size of salt crystals is misleading because solubility refers to the maximum amount of solute that can dissolve in a given amount of solvent at a specified temperature, and it is the same for both coarse and fine salt as denoted in statement D) Both coarse and fine salt are equally soluble.
