CARBON(II) OXIDE
LABORATORY PREPARATION OF CO [in the fume cupboard]
Three methods can be used to prepare CO in the lab and they are as follows;
The equation for the reaction is given as shown below;
H2C2O4.2H2O(s) decomposed → 3H2O(l) + CO(g) + CO2(g)
Note: That conc. H2SO4 is a drying agent, it is there to remove the elements of water while KOH removes CO2(g)
CO2(g) + 2KOH(aq) → K2CO3(aq) + H2O(l)
2(a) Sodium Methanoate crystals
2HCOONa(s) + H2SO4(aq) → Na2SO4(aq) + 2H2O + 2CO(g)
HCOOH(l) → CO(g)
Show that H2SO4 removes water, a dehydrating agent
CO2(g) + C(s) → 2CO(g)
PHYSICAL PROPERTIES OF CO
CHEMICAL PROPERTIES AND USES OF CO
Note: The product of combustion or oxidation of CO is CO2; confirmed by its ability to turn lime water milky.
