Q:

What factors affect the solubility of a substance?

A:

Quick Answer

Temperature, pressure and substance composition can impact the solubility of a substance. Reactions between solutes and solvents can decrease the solubility of a substance as well.

Full Answer

The solubility, or the amount of a substance that can be dissolved in a given solvent, varies based on a variety of factors. Solids, gases and liquids all have different levels of solubility.

Le Chatelier's principle explains why and how substances become more soluble. The principle notes that when a chemical equilibrium is under stress, it will react in a different manner to handle the stress.

Each of these states reacts differently with temperatures and pressures, which can increase or decrease the solubility. For instance, gases that are exposed to decreasing temperatures, will be more likely to have higher solubility than at those that are lower. There are no temperatures that provide a measured effect on a liquid's solubility.

  • Q:

    How does polarity affect solubility?

    A:

    Polar substances tend to dissolve well in other polar substances, but not nonpolar substances, while nonpolar substances dissolve well in nonpolar substances, but not polar substances. This concept is often referred to as "like dissolves like."

    What factors affect solubility?

    A:

    The temperature, the polarity of the solutes and solvent, the pressure, and the molecular size affect solubility. All of these factors play roles in determining which solutes dissolve in which solvents.

    At what temperature does glass shatter?

    A:

    Temperature is not the only factor that determines when glass breaks, as the speed in which the glass is heated, as well as the distribution of heat, play a large role in determining expansion and contraction of glass which can ultimately cause shattering and cracks. Known as a thermal break, applying heat to glass can cause it to crack or shatter.
