Describe

AQUEOUS SOLUTIONS IN TERMS OF SOLUTE AND SOLVENT CONCENTRATION AND DILUTION

Including, but not limited to:

• Solutions – a mixture of one kind of particles (atoms and molecules) dissolved in another, different type of particles (atoms and molecules)

  • Aqueous (solution) – a solution with water as the solvent 

    • Saltwater solution

    • Sugar water solution

    • Lemon water solution

  • Solute – a substance that is dissolved into another substance

    • Salt

    • Sugar

    • Lemon juice

  • Solvent – a substance which another substance is dissolved in 

    • Water

  • Concentration – the amount of solute that is dissolved in a specific amount of solvent

    • Concentrated – a solution that contains a high amount of solute

    • Saturated – a solution that contains the maximum amount of dissolved solute that a solution can hold 

    • Diluted – a solution that contains a low amount of solute 

  • Dilution – the process of reducing the concentration of solute / solvent in a solution by adding more solvent (water)

Note(s):

• Focus is using descriptive language to express conceptual understanding of the relative strengths of solutions made with water. 

  • Calculations of concentrations and dilutions will occur with concentrations made in high school.
