Net Ionic Equations

Do All Double Replacement Reactions Occur? (DEMO) Sodium chloride + silver nitrate  Sodium chloride + potassium nitrate 

Why Don’t We See A Reaction? Sometimes everything formed is soluble and dissolved in water so we don’t see it Solubility charts give us an idea of what is soluble and what is not

Are These Soluble? Ca(OH) 2 KBr PbCl 2 Na 3 (PO 4 ) 2 MgCO 3

Will The Reactions Below Occur? If the reaction occurs, write the products formed. If not write “no reaction” NaCl + KBr  Pb(NO 3 ) 2 + ZnCl 2  K 2 SO 4 + CaCl 2 

Net Ionic Reaction Shows only the part of a replacement reaction that is actually seen Break down all soluble substances into their ions Cancel out ions the same on both sides of an equation – called spectator ions

Write Net Ionic Reaction BaCl 2 + K 2 SO 4  Na 2 CO 3 + Ca(OH) 2 

If the reactions below occur, write the net ionic equation. If not write, “no reaction” NaNO 3 + KBr  BaCl 2 + H 2 SO 4  CaBr 2 + Na 2 CO 3  Ag(NO 3 ) + NaCl 
