What determines a compounds solubility?
Definition of Solubility The solubility of a substance fundamentally depends on the solvent used, as well as temperature and pressure. The solubility of a substance in a particular solvent is measured by the concentration of the saturated solution. The term “insoluble” is often applied to poorly soluble compounds.
How do you know which compounds will dissolve in water?
Water is a polar compound, and only “like dissolves like”. Meaning if the solute is a polar compound (in general, not intramolecular forces), then it will dissolve. You can determine the general polarity by identifying its molecular shape. If it’s symmetrical, it is non-polar.
What determines whether a substance will dissolve in a solvent?
What determines whether a substance will “dissolve”? The “compositions of the solvent and the solute” determine whether a substance will “dissolve”.
What 2 factors determine whether a substance will dissolve?
Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
How do you know which compound is more soluble?
Substances with similar polarities tend to be soluble in one another (“like dissolves like”). Nonpolar substances are generally more soluble in nonpolar solvents, while polar and ionic substances are generally more soluble in polar solvents.
Which solute will dissolve the quickest?
A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk because more surface area is exposed. The packet of granulated sugar exposes far more surface area to the solvent and dissolves more quickly than the sugar cube.
What is not a factor that determines how fast a substance will dissolve?
Whether or not a substance dissolves depends upon the nature of the solvent and the solute. Factors that determine how fast a substance dissolves are stirring, temperature, and surface area. Solubility is usually expressed in grams of solute per 100 g of solvent.
