2. Write balanced complete ionic equations for the following reactions. In each case, use the so1ubi1ity rules to determine whether or not either or both of the reaction products is water soluble. (a) CaCl2(aq) Na2SO4(aq) ?> NaCl( ) + CaSO4( ) (b) BaCl2(aq) + AgNO3(aq) ---> AgCl( ) + Ba(N03)2( ) (c) NH4NO3(aq) + Pb(ClO4)2(aq) ---> Pb(NO3)2( ) + NH4ClO4( ) (d) AlCl3(aq) + K2CO3(aq) ----> Al2(C03)3( ) + KCl( ) (e) Na3PO4(aq) + AgNo3(aq) ---> Ag3PO4( ) + NaNO3( ) 3. Write the balanced net ionic equations for the reactions represented in Problem Set 7, Problem 2 that produce precipitates.

Explanation / Answer

A) Na2SO4(aq) + CaCl2(aq) ---> CaSO4(s) + 2NaCl(aq)

B)BaCl2(aq) + 2 AgNO2(aq) ---> Ba(NO3)2(aq) + 2AgCl(s)

C)NH4NO3+Pb(ClO4)2=NH4(ClO4)2+Pb(NO3)2

D)2 AlCl3(aq) + 3 K2CO3(aq) ? 6 KCl(aq) + Al2(CO3)3

E) AgNO3(aq)+Na3PO4(aq)=Ag3PO4(s)+NaNO3(aq)
