Poster Project: (In groups of 2 -3) Create a poster of your assigned inorganic compound
What is your compound? Define / describeWhat are some important properties of your compound?What role/function does your compound play in the body?Be creative: Include appropriate drawings, diagrams, formulas, etc.
Gallery Walk
Spend time viewing the other three inorganic compound posters and take notes accordingly
Write directly in your notes
Rotate to the next station when instructed
Important Inorganic Compounds
SaltsEasily dissociate into ions in the presence of water
Vital to many body functions
Include electrolytes which conduct electrical currents
Dissociation of a Salt in Water
Important Inorganic Compounds
AcidsRelease hydrogen ions (H+)Are proton donors
BasesRelease hydroxyl ions (OH–)Are proton acceptors
Important Inorganic Compounds
Neutralization reactionAcids and bases react to form water and a salt
pHMeasures relative concentration of hydrogen ions
pH 7 = neutral
pH below 7 = acidic
pH above 7 = basic
Buffers—chemicals that can regulate pH change
1) Identify each of the following reactions as a synthesis, decomposition, or exchange reaction:
2Hg + O2 2HgO
Fe 2+ + CuSO4 FeSO4 + Cu2+
HCl + NaOH NaCl + H2OHNO3 H+ + NO3

3) The two oxygen atoms forming molecules of oxygen gas that you breathe are joined by a polar covalent bond. Explain why this statement is true or false
4) Oxygen and argon are both gases. Oxygen combines readily with other elements, but argon does not. What accounts for this difference?
