AgNO3 (aq) + NaCl(aq) AgCl(s) + NaNO3(aq)

What happens when you put

AgNO3 and NaCl in water?


Agno 3 aq nacl aq agcl s nano 3 aq

AgNO3 (aq) + NaCl(aq) AgCl(s) + NaNO3(aq)

What really happens when you put

AgNO3 and NaCl in water?


Agno 3 aq nacl aq agcl s nano 3 aq

KEY POINT:

NaCl (aq)

really means:

Na +1(aq) + Cl -1(aq)

“dissociated ions”

or

“ions in solution”


What is dissolving

What is Dissolving ?

When an ionic compound (eg salt) dissolves in water, the compound disassociates. (breaks apart into cations and anions)

Ex: Ca(NO3)2(s)Ca2+(aq) + 2NO3-(aq)

When a covalent compound (eg sugar) dissolves in water, the molecules simply disperse; they do not disassociate. Molecules of the covalent compounds simply disperse due to attraction with polar water molecules.

net ionic equation


Agno 3 aq nacl aq agcl s nano 3 aq

  • Complete molecular equation-

    • describes double replacement reaction

  • Complete ionic equation-

    • more accurately shows the reacting species as ions and the products either as ions or a precipitate

  • Net ionic equation-

    • focuses only on the ions REACTING

  • Spectator ions are those ions that do NOT participate in the reaction


Predicting the formation of a precipitate

PREDICTING THE FORMATION OF A PRECIPITATE

  • Consider the possibility that a precipitate may form.

  • Must use the solubility table on page 227 to decide.

  • Possible outcomes

    • No visible reaction (nvr)

    • Formation of one ppt.

    • Formation of two ppt. (rare occurrence)

Basic Chemical equation AgNO3(aq) + KCl(aq)AgCl(s) + KNO3(aq)

Complete ionic equation shows ions in solution Ag+ (aq)+NO3(aq) + K+ (aq)+Cl-(aq)AgCl(s) + K+ (aq) + NO3-(aq)

Net ionic equation shows ions in rxn Ag+ (aq)+Cl-(aq)AgCl(s)

(leave out spectator ions)
