Question

Write net ionic equations for the reaction, if any, that occurs when aqueous solutions of the following are mixed. ammonium sulfate and barium nitrate Answer ‍ ‍ ‍ ; lead(II) nitrate and sodium chloride Answer ‍ ‍ ‍ ‍ ; sodium phosphate and potassium nitrate Answer no reaction; sodium bromide and rubidium chloride Answer no reaction; copper(II) chloride and sodium hydroxide Answer ‍ ‍ ‍ ‍ ‍

Answer 1

Answer:

See explanation for details

Explanation:

ammonium sulfate and barium nitrate Answer ‍

Ba2+(aq) + SO4^2-(aq) ----------> BaSO4(s)

lead(II) nitrate and sodium chloride Answer ‍

Pb2+(aq) + 2Cl-(aq) -----------> PbCl2(s)

copper(II) chloride and sodium hydroxide Answer ‍ ‍ ‍ ‍ ‍

Cu2+(aq) + 2OH-(aq) -------------> Cu(OH)2(s)

There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.
