Solution

• Solution


  A homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility
• The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible
• Solutions


  • Air
  • Brass
• Solutions


  • Oxygen from the lungs goes into solution in the blood plasma, unites chemically with the hemoglobin in the red blood cells, and is released to the body tissues
  • The products of digestion also are carried in solution to the different parts of the body
  • Chemists take advantage of differences in solubility to separate and purify materials and to carry out chemical analysis
  • Most chemical reactions occur in solution and are influenced by the solubilities of the reagents
  • Materials for chemical manufacturing equipment are selected to resist the solvent action of their contents
• Solvent


  The liquid in a solution
• Solute


  The substance added to the solvent
• Concentration


  May be expressed in units of weight, volume, or moles
• Electrolyte


  A solution that can conduct electricity, where the solute is made up of ions that are free to migrate to charged electrodes
• Nonelectrolyte


  A solution where the solute is made up of simple, nonpolar molecules and has very different properties from electrolytes
• At high pressures, pairs of chemically dissimilar gases may exhibit only limited miscibility
• Many different metals are miscible in the liquid state, occasionally forming recognizable compounds
• Some metals are sufficiently alike to form solid solutions (alloys)
