Net Ionic Equations. 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.

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 • PbCl2 • Na3(PO4)2 • MgCO3
Will The Reactions Below Occur? • If the reaction occurs, write the products formed. If not write “no reaction” • NaCl + KBr • Pb(NO3)2 + ZnCl2 • K2SO4 + CaCl2
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 BaCl2 + K2SO4 Na2CO3 + Ca(OH)2
If the reactions below occur, write the net ionic equation. If not write, “no reaction” NaNO3 + KBr BaCl2 + H2SO4 CaBr2 + Na2CO3 Ag(NO3) + NaCl
