How many Strong Acids (SA) are there? WHy is it important to know them? List all of them:	7 Total; Anything that is not a on this STRONG ACID Team Roster does not make the cut; they are not a strong acid. 1) HCL 2) HBR 3) HI 4) H2SO4 5) HNO3 6) HCLO4 7) HClO3
How many strong bases are there ? LIst them all:	8 LiOH NaOH KOH RbOH CsOH Ca(OH)2 Sr(OH)2 Ba(OH)2
What are the most common weak bases?	NH3 or Amines
What are Binary Acids? And what are the trends?	Acids made of only 2 elements: 1) H+ and 2) Something else Trend: Periodic table C N O F Cl Br I Size: Acid strength increase going down the periodic table (more stable conjugate base b/c of size) Electronegativity: Acid Strength increases when going from L to R. Examples: HCl, HBr etc...just two elements.
WHat are oxoacids?	1. contains oxygen 2. contains at least one other element 3. has at least one hydrogen atom bound to oxygen 4. forms an ion by the loss of one or more protons
What is the oxoacid trend? What are some examples of strong oxoacids?	1) More oxygen = more acidic ie. HClO2 < HClO3 < HClO4 Also, more oxygen stabilizes the CB, making the CB more weak = strong acid. 2) More electronegative the heteroatom (different element) = more acidic i.e. HIO3 < HBrO3 < HClO3 CB IO3- lest stable than BrO3- and is less stable than ClO3- ...b/c the Cl- atom is the most electronegative which stabilizes the other oxygen atoms better. Less negative = weak base.
What is a titration?	Used to find the concentration or Molarity (moles/L)
