Chemistry

• Solution


  Is a homogenous mixture of two or more substances
• Solute


  Is the substance present in the smaller amount
• Solvent


  Is the substance present in the larger amount
• Saturated solution


  contains the maximum amount of a solute that will dissolve in a given solvent at a specific temperature; particles at the bottom
• Unsaturated solution


  Contains less solute than the solvent has the capacity of dissolve at a specific temperature; completely dissolve at the bottom
• Supersaturated solution


  Contains more solute than is present in a solution at a specific temperature; crystals at the bottom
• Solution process


  In order for a solute to be dissolved in a solvent, the solute and solvent must be attracted to each other
• ENERGY CHANGES IN SOLUTION: To determine the enthalpy change, we divide the process into 3 steps 1. Separation of solute particles. 2. Separation of solvent particles to make holes. 3. Formation of new interactions between solute and solvent
• Concentration


  The amount of solute present in a given quantity of solvent or solution
• Concentrated solution


  One in which there is a large amount of solution in a given amount of solvent or solution
• Dilute solution


  One in which there is a small amount of solute in a given amount of solvent
• Dilution


  The procedure for preparing a less concentrated solution from a more concentrated solution
• Titrations


  A solution of accurately known concentration is added gradually to another solution of unknown concentration until the chemical reaction between the two solutions is complete
• Equevalence point


  The point at which the reaction is complete
• Indicator


  Substance that changes color at the equevalent point
