(c) Report the balanced chemical
equation.
H2C2O4 (aq) +NaOH(aq) Na(g)
+ H3C2O5 (g)
Report
The
balanced chemical equation is an indication that the both reduction and
addition took place. The sodium hydroxide was reduced into the sodium metal,
thus reducing its mass. However, the crystalline carboxyl acid received two
elements of carbon and four elements of oxygen resulting into a different
compound H3C2O5
(g) which
is gaseous in nature thus increasing in weight.
