Chapter 7 Flashcards
Arrhenius definition of acids
Ionize in water to form H ions.
-Actually, the H from the acid molecules is donated to a water molecule to form hydronium ions
Arrhenius definition of bases
Bases dissociate in water to form OH ions
- weak bases in (NH3) do not contain OH ions…
Strong Acids
Strong acid: one that completely dissociates to product H3O
- the acid will not be found, only the ions do
memorize strong acids and bases
HBr hydrobromic acid
HCl hydrochloric acid
HI hydroiodic acid
HNO3 nitric acid
HClO4 perchloric acid
H2SO4 sulfuric acid
weak acids
An acid where only a small amount reacts to form H30
Strong base
an ionic compound with OH as the anion
LiOH
NaOH
KOH
Ca(OH)2
Sr(OH)2
Ba(OH)2
Weak base
a compound that reacts with water to produce a small amount of OH
Neutralization reaction
acid-base or neutralization reaction
Acid + base = water + salt
Oxidation-reduction reaction
electrons are transferred but never seen in the overall reaction so they are written in half reactions
Some thing is considered an acid becase?
it produces hydronium ions in solution.
Quantitative analysis:
the determination of the amount or concentration of a substance in a sample
Gravimetric analysis:
weighing the final product obtained from some physical or chemical change, and from this, determining the amount of analyte present in a sample
