H+(aq) + NH3(aq)→ NH4+(aq) Acids (memorize !) (memorize Strong Acids Examples: Strong acids are almost completely ionized in water. (strong electrolytes) (strong 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 (weak electrolytes) Weak acids are governed by dynamic equilibrium. 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 Strong Bases: A base is a substance that produces OH– (aq) ions in water by dissociation in water: + − NaOH(s)...
