Answer 1

Write the net ionic equations for each reaction

Iron (III) chloride + Sodium hydroxide

FeCl3(aq) + 3NaOH(aq) = Fe(OH)3(s) + 3NaCl(aq)

net ionic

Fe3+(aq) + 3OH-(aq) = Fe(OH)3(s)

Hydrochloric acid + Sodium hydroxide

HCL(aq) + NaOH(aq) = H2O(l) + NaCl(aq)

H+(aq) + OH-(aq) = H2O(l)

Copper (II) sulfate + Sodium phosphate

3CuSO4(aq) + 2Na3PO4(aq) = Cu3(PO4)2 + 3Na2SO4(aq)

3Cu2+(aq) + 2PO4-3(aq) = Cu3(PO4)2

Potassium carbonate + Hydrochloric acid

K2CO3(aq) + 2HCl(aq) = H2O(l) + CO2(g) + KCl(aq)

net ionic

CO3-2(aq) + 2H+(aq) = H2O(l) + CO2(g)

Q2

Ag+, Pb2+, Fe3+, Sr2+, Na+

a) hydroxide

AgOH, Pb(OH)2, Fe(OH)3 , Sr(OH)2

b) phosphate

Ag3PO4, Pb3(PO4)2, FePO4, Sr3(PO4)2

c) sulfide

Ag2S, PbS, FeS, SrS

d) bromide

AgBr, PbBr2
