PH Mini Lab
Posed Question:  What are the PH levels of 5 items around the house.
(students will each bring in 1 or 2 item from their home to test the PH level)

Hypothesis:  In testing 5 household items, ________, ________ and _______ will test to be acids while ______ and ___________ will test to be bases.

Design an Experiment:
    Materials 
  • List your 5 items here
  • Forceps
  • Dropper
  • Hydrion Paper
  • Beakers
   Procedure
  1. Holding the hydrion paper with the forceps dip an unused paper into one of the 5 items.
  2. Compare the color of the hydrion paper to the pH scale to determine if it is an acid, base or neutral.
  3. Repeat steps 1 and 2 with a new hydrion paper and another item.


Collect Data
(Items will be different depending on what students brought in to test.)

Picture

Homework:
Bring in your item to test for tomorrow's pH lab
Announcement:
Don't forget to bring in your item to test in the lab!

EQ:  What are the properties and uses of acids and bases
Picture



Cornell Notes: "Describing Acids and Bases"

Properties of Acids
Acid:  
  • Sour Taste 
                     Citrus Fruits (sour) are acidic:              ****Acids should not be identified by taste***
                     *Lemons                                                                                     Unsafe!!!
                     *Grapefruit
                     *Oranges
                     *Limes
  • Reactions with Metals
                     Corrosive:  wears metals away.  Destroys!
                     Acids react with certain metals                   
                     *Magnesium
                     *Zinc
                     *Iron
  • Reactions with Carbonates
                    Acids react with negative carbonate ions to produce carbon dioxide gas.
                    Limestone contains a carbonate ion - reacts with acids (bubbles/gas)

  • Reactions with Indicators



Homework:

Finish Cornell Notes on Chapter 7 Section 3.
Notes will be stamped tomorrow at the beginning of class.
Announcements:

There are 2 assignments in this NEW MARKING PERIOD! If you only turn in 1 out of 2 you automatically have an "F".

Cornell Notes:  finish "Solutions, Colloids and Suspensions"

Suspensions:  
  • Contains particles larger than the particles in a colloid and a solution.
  • Particles can be seen easily and separated by settling or filtration.
  • Does not have the same properties throughout.
New Vocabulary:
  1. Concentrated solution:  Large amounts of a solute in a solution.  
  2. Dilute Solution:  Low amounts of a solute in a solution.  For example, adding water to orange juice produces a diluted orange juice solution.
  3. Solubility:  How much solute can dissolve in a solvent.  
  4. Unsaturated Solution:  Solute can still be dissolved in the solvent.  For example, water is a unsaturated solution because I can add sugar or salt to the water and it will still dissolve.
  5. Saturated Solution:  Solute cannot dissolve in the solvent.  For example, 3 cups of sugar in 1 cup of water is a saturated solution.  The sugar will not dissolve in such a small amount of water.
  6. Supersaturated Solution:  When heated a solution can dissolve more solute than at a cooler temperature. For example, when heated I can dissolve 3 cups of sugar into 1 cup of water.

Homework:  
poster of "Solutions/Colloids/Suspensions"
Directions:
  • Divide paper into 3 sections
  • Title each section as a solution, colloid or suspension.
  • Draw an example for each type of mixture.
  • Give 2 characteristics for each type of mixture.
  • For the solution - label the solute and the solvent.
  • You may NOT use saltwater/muddy water/ or sugar water for any of your examples
