Net Ionic Equations

• Single Replacement reactionsMg + CuCl2 → Cu + MgCl2

What doesn’t change?

Chloride

What changes?

Mg + Cu+2 → Cu + Mg+2

this is the net ionic equation

Mg + CuCl2 → Cu + MgCl2

• In solution:

• Mg + Cu+2 +2Cl-1

– Magnesium metal, Cu+2, Cl-1

• After what ions are in solution– Cu, Mg+2, Cl-1

Na + HCl produces?

• What is the reaction?– Na + HCl → NaCl + H2

• What is the net ionic equation?– Na + H+ → Na+ + H2

Double Replacement

• AgNO3 + NaCl →?

Ag+ + Cl- → AgCl

sulfurous acid is mixed with calcium metal to yield?

zinc (II) acetate is mixed with gold metal
