Question

Balance and state if the following reactions are Precipitation, Acid/Base, or Oxidation/Reduction reactions. a) Fe_(s) + O_2(g) rightarrow Fe_2 O_3(s) Precipitation, Acid/Base, or Oxidation/Reduction? _______________ b) I_2(s) + Fe(NO_3)_2(aq) + KNO_3(aq) rightarrow KI_(aq) + Fe(NO_3)_3(aq) Precipitation, Acid/Base, or Oxidation/Reduction? _________________ c) NaOH_(aq) + H_2 CO_3(aq) rightarrow H_2 O_(l) + Na_2 CO_3(aq) Precipitation, Acid/Base, or Oxidation/Reduction? _____________ d) NaF_(aq) + Mg(NO_3)_2(aq) rightarrow MgF_2(s) + NaNO_3(aq) Precipitation, Acid/Base, or Oxidation/Reduction? ______________ There are times when an acid/base reaction is also a precipitation reaction. Give an example of two reactants you could combine that would produce such a result.

Explanation / Answer

1a) oxidation/reduction reaction, here iron is getting oxidizes and oxygen is getting reduced

B) oxidation/reduction reaction, here iron(II) is getting oxidizes to Iron(III) and iodine is getting reduced

C) acid/base reaction, NaOH act as a base and H2CO3 as acid

D) precipitation reaction as magnesium fluoride is getting precipitated

2. Ca(OH)2 (aq)+ H2CO3 (aq) -----> CaCO3 (s) + 2H2O (l)

This is an example of acid /base reaction Where precipitation occurs
