HX(aq) + H2O(l)→ H3O+(aq) + X–(aq)
H3O+(aq) = H+(aq) • A base is any substance that accepts an H+
(aq) in an aqueous solution.
H+(aq) + NH3(aq)→ NH4+(aq) Acids (memorize !)
(memorize Strong Acids
Examples: Strong acids are almost completely ionized in
water. (strong electrolytes)
HX (aq) (X = Cl, Br & I) hydro ___ ic acid
HNO3 (aq) nitric acid HClO4 (aq) perchloric acid H2SO4 (aq)* sulfuric acid * Only the 1st H is strong, sulfuric acid dissociates via:
H2SO4 (aq) → H+ (aq) + HSO4– (aq) Acids
An acid: H3O+ in water
An Weak Acids
Examples: Weak Acids are incompletely ionized in water.
(weak electrolytes) Weak acids are governed by
HC2H3O2 (aq) acetic acid (vinegar) nitrous acid HNO2 (aq) hydrosulfuric acid H2S (aq) hydrogen sulfate ion HSO4–(aq) Weak acids are always written in their molecular form.
always See your text and home work for more examples. Strong Bases
Bases: A base is a substance that produces OH– (aq) ions in
water by dissociation in water:
+ − NaOH(s)...
