To the wonderful world of acids and bases we go!!!
AcidsCan be a solid liquid or gas at
SATP*
*SATP
=> A really fancy way of saying 25 Degrees Celcius or 100kPa
Form conducting aqueous solutions
Turn blue litmus paper to red
Dissolve in water to produce H+
Taste Sour
Naming AcidsAcids are aqueous(dissolved in water)
Hydrogen compounds are acids
=>HCl(aq) -> Hydrochloric Acid
=>H2SO4(aq) -> Sulfuric Acid(IMPORTANT)
Hydrogen appears first in the formula unless it is part of a polyatomic group
=>CH3COOH(aq) -> Acetic Acid
Classical rules use suffix
-ic and/or the prefic
hydro- =>Hydrochloric Acid
IUPAC system uses the aqueous hydrogen compound
=>HCl(aq) -> Aqueous Hydrogen Chloride
BasesTurn red litmus blue
Slippery
Nonconductive
Dissolve water to produce OH-
Naming BasesFor now, all bases will be aqueous solutions of ionic hydroxides
=>NaOH
=>Ba(OH)2
Use the cation name followed by hydroxide
=>Sodium Hydroxide
=>Barium Hydroxide
Examples
HI(aq) -> Aqueous Hydrogen Iodide/Hydroiodic Acid
H3PO4(aq) -> Phosphoric Acid
=>H3PO3 -> Phophorous Acid
HNO3(aq) -> Nitric Acid
=>HNO2 -> Nitrous Acid
Mg(OH)2 -> Magnesium Hydroxide
HBr(aq) -> Hydrobromic Acid/Aqueous Hydrogen Bromide
HOOCCOOH(aq)(TRICKEY) -> Oxalic Acid(Pretty small name for a big formula, eh?)
