Question

*4 PARTS* Write the balanced chemical, ionic, and net ionic equations for the following reactions, and identify what type of reaction it is (precipitation, redox, or acid-base neutralization.

a) The reaction of sulfuric acid with sodium bicarbonate.

b) The reaction of silver nitrate with iron (III) chloride.

c) The reaction of aqueous sodium sulfide with aluminum nitrate.

d) The reaction of sulfur dioxide with oxygen to produce sulfur trioxide. (Hint: these are all gasses; this is an oxidation/reduction reaction.

Explanation / Answer

a. H2SO4(aq) + Na2CO3(aq) ------> Na2SO4(aq) + H2O(l) + CO2(g)

2H+ +SO42-(aq) + 2Na+ +CO32-(aq) ------> 2Na++SO42-(aq) + H2O(l) + Co2(g)

removal of spectator ions

2H+ +SO42-(aq) + CO32-(aq) ------> H2O(l) + Co2(g) net ionic equation

b. 3AgNO3(aq) + FeCl3(aq) ------> 3AgCl(s) + Fe(NO3)3(aq)

3Ag+(aq)+3NO3-(aq) + Fe+3(aq) + 3Cl-(aq) ------> 3AgCl(s) + Fe+3+ 3(NO3)-(aq)

removal of spectator ions

3Ag+(aq)+   3Cl-(aq) ------> 3AgCl(s) net ionic equation

C. 3Na2S(aq) + 2Al(NO3)3 (aq) ------> Al2S3 (s) + 6NaNO3

6Na+(aq) + 3S-2(aq) + 2Al+3(aq) + 6(NO3)-(aq) ------> Al2S3 (s) + 6Na+(aq) + 6NO3-

Removal of spectator ions

3S-2(aq) + 2Al+3(aq) ------> Al2S3 (s)   net ionic equation

d.2 So2 + O2 -----> 2SO3

sulphur O.N increases from +4 to +6. This is oxidation

oxygen zero to -2 decreases. It is reduction
