concentration of solutions

• SOLUTE:

  • A solid substance that dissolves in a liquid

  SOLVENT:

  • The liquid it dissolves in

  SOLUTION:

  • The mixture that a SOLUTE and SOLVENT form
• CONCENTRATION:

  The AMOUNT OF A SUBSTANCE within a certain VOLUME of solution.

  • The more SOLUTE there is in a given volume, the more concentrated the solution is.
• Volume can be measured in cm3 or dm3.

  • You can CONVERT between the two by multiplying & dividing by 1000
  • Concentration is typically measured in grams per decimetre cubed (g/dm³).

  
• 1cm = 1000dm
• Concentration (g/dm^3) = Mass (g) / volume (dm3)
• • Concentration (g/dm^3) = Mass (g) / volume (dm3)
  • Mass (g) = Concentration (g/dm^3) x volume (dm3)
  • Volume (dm3) = Mass (g) / Concentration (g/dm^3)
