1st QTR L3 GR7

• is a homogenous mixture

  solution
• what are the 2 components of solution?


  solute and solvent
• component that is being dissolved

  solute
• the dissolving agent


  solvent
• alloy is made of

  carbon and iron
• Brass is made of

  copper and zinc
• the universal solvent


  water
• what are the 3 factors that affect the rate of dissolution


  stirring, particle size and temperature
• facilitates the fast dispersion of solute and solvent particles in a solution

  stirring
• The concentration of a solution can be expressed qualitatively and quantitatively (true or false)

  true
• it is not important to understand the ways of expressing concentration (true or false)

  false
• it is important to understand the ways of expressing concentration (true or false)

  true
• contains small amounts of solute

  dilute
• contains larger amount of solute

  concentrated
• what are the 3 degrees of saturation?


  unsaturated, saturated and super saturated
• A solution that has dissolved as much solute as it is capable of dissolving


  saturated
• Dissolve solute is below saturated point; more solute can dissolve


  unsaturated
• Dissolve solute is above saturated point; additional solute gathers together at the bottom only

  super saturated
• Concentrations can be expressed by percent of mass, which all mass measurements to have the same units of measure

  percent by mass
• Liquid solutions are often expressed as volume percent or percent by volume

  percent by volume
