Solubility and Solutions - Chemistry

• Solubility


  Ability of a substance to dissolve in water.
• Solute


  Solid that dissolves in a solvent.
• Solvent


  Liquid that dissolves the solute.
• Solution


  Homogeneous mixture of solute and solvent.
• Saturated Solution


  Cannot dissolve more solute in solvent.
• Buoyancy


  Ability of an object to float in fluid.
• Temperature Effect


  Higher temperature increases solute dissolution speed.
• Solubility Graph


  Visual representation of solubility vs temperature.

  
• Seawater Salt Concentration


  Mass of salt in seawater, typically 35g/L.
