Ionic Compounds and Strong Acids
Dissociate – break apart into ions. Each ion is surrounded by water.
2 aqueous (aq) reactants
1 solid and 1 aqueous product
*You must learn solubility rules in order to predict the solid product formed in a precipitation reaction
How do the ions in a dissolved compound compare to those in an insoluble one?
DON’T FORGET TO BALANCE!
HCl(aq) + NaOH(aq) H2O(l) + NaCl(aq)
* Notice how similar this reaction is to a precipitation reaction.
Consider the reaction below:Pb(NO3)2(aq) + 2NaI(aq) PbI2(s) + 2NaNO3(aq)
Pb2+(aq) + 2I-(aq) PbI2(s)
Cu(s) + Mg2+(aq) No Reaction
Mg(s) + Cu2+(aq) Mg2+(aq) + Cu(s)
Molarity as conversion factor
