Solubility & Concentration

Solubility & Concentration. Matthew Robob & Trav P . Solubility is the max amount of a solute that dissolves in a given amount of a solvent, & the constant temp. Solutions- are described as saturated unsaturated, or super saturated, depending on the amount of saluted solution.

  1. Solubility & Concentration Matthew Robob & Trav P.

  2. Solubility is the max amount of a solute that dissolves in a given amount of a solvent, & the constant temp.

  3. Solutions- are described as saturated unsaturated, or super saturated, depending on the amount of saluted solution.

  4. Saturated solutions- is one that contains as much solute as the solute can hold as a certain temp. when a solution is saturated the solvent can also be called “filled”.

  5. Unsaturated solutions- a Solution that has less then the max amount of solvent that can be dissolved.

  6. Super Saturated- is one that contains more saluted that it can normally hold at a given temp.

  7. Polar Solvents- have large dipole moments (aka “partial charges”); they contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen.

  8. Non polar solvents contain bonds between atoms with similar electronegativities, such as carbon and hydrogen (think hydrocarbons, such as gasoline). Bonds between atoms with similar electronegativities will lack partial charges; it’s this absence of charge which makes these molecules “non-polar”.

  9. In general, the solubility of solids increases as the solvent temp. increases.

  10. Unlike most solids, gases usually become less soluble as the temp. of the solvent increases.

  11. They use pressure to force carbon dioxide or (CO2) to dissolve in the liquid. • Increasing the pressure inside the gas, increases the solubility in a liquid.

  12. Concentration- is defined as the abundance of a constituent divided by the total amount of a mixture.

  13. Concentration is also expressed by the percent of volume, mass, and molarity.
