1. Write the formulas of the principal molecular or ionic species present in an aqueous solution of each substance.
(a) Sodium Chloride, NaCl
Na+ + Cl-
(b) Hydrogen bromide, HBr

(c) Iron (III) sulfate, Fe2(SO4)3

(d) Ethanol, CH3CH2OH

(e) Glucose, C6H12O6

(f) Ammonium acetate, NH4CH3COO

  • Chemistry -

    HBr is a strong acid and ionizes 100%.
    Fe2(SO4)3 is completely soluble in water and is present as the ions.
    Same for CH3COONH4
    The others are ok.

    2. What are spectator ions in chemical reactions

  • Chemistry -

    The spectator ions are those that cancel when writing the net ionic equation. For example, an acid/base reaction between HCl and NaOH is
    HCl(aq) + NaOH(aq) ==> NaCl(aq) + H2O(l)

    We turn that into an ionic equation--you can add the aq part to each.
    H^+ + Cl^- + Na^+ + OH^- ==> Na^+ + Cl^- + H2O
    You see Cl^- is on both sides and those cancel.
    You see Na^+ on both sides. Cancel them.
    That leaves
    H^+(aq) + OH^-(aq) ==> H2O(l) as the net ionic equation. The Na^+ and Cl^- are spectator ions.
