the reaction of sodium phosphate (Na3PO4) solution with lead (II) chlorate [Pb(ClO3)2] solution produces a precipitate. Give the balanced molecular equation for this reaction


Expert Answer

Step 1

Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate.

 Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.


Step 2

Solubility rules:

  • Salts formed with group-1 cations and NH+4 cations are soluble. There are some exceptions for certain Li+
  • Acetates (C2H3O2-), nitrates (NO3-), and perchlorates (ClO4-) are soluble.
  • Bromides, chlorides, and iodides are soluble.
  • Sulfates (SO4-2) are soluble with the exception of sulfates formed with Ca2+, Sr2+, and Ba2+.
  • Salts containing silver, lead, and mercury (l) are insoluble.
  • Carbonates (CO3-2), phosphates (PO4-3), sulfides, oxides, and hydroxides (OH-) are insoluble. Sulfides formed with group-2 cations and hydroxides formed with calcium, strontium, and barium are exceptions.

If the rules state that an ion is soluble, then it remains in its aqueous ion form. If an ion is insoluble based on the solubility rules, then it forms a solid with an ion from the other reactant. If all the ions in a reaction are shown to be soluble, then no precipitation reaction occurs.
