Silver oxalate is an inorganic compound, a salt of a metal of silver and oxalic acid with the formula Ag ₂ C ₂ O ₄ /

Content

Getting

The exchange reaction of alkali metal oxalates with silver nitrate (I) :

{\mathsf {2AgNO_{3}+Na_{2}C_{2}O_{4}\ {\xrightarrow {}}\ Ag_{2}C_{2}O_{4}\downarrow +2NaNO_{3}}}

{\ displaystyle {\ mathsf {2AgNO_ {3} + Na_ {2} C_ {2} O_ {4} \ {\ xrightarrow {}} \ Ag_ {2} C_ {2} O_ {4} \ downarrow + 2NaNO_ {3 }}}}

Physical Properties

Silver oxalate forms colorless crystals of monoclinic syngony , space group P 2 ₁ / c , cell parameters a = 0.3460 nm, b = 0.6197 nm, c = 0.9548 nm, β = 103.47 °, Z = 2.

Not soluble in water. Sensitive to light. When heated to 140 ° C decomposes with an explosion.

Chemical Properties

Decomposes on heating:

{\mathsf {Ag_{2}C_{2}O_{4}\ {\xrightarrow {100^{o}C}}\ 2Ag+2CO_{2}\uparrow }}

{\ displaystyle {\ mathsf {Ag_ {2} C_ {2} O_ {4} \ {\ xrightarrow {100 ^ {o} C}} \ 2Ag + 2CO_ {2} \ uparrow}}}
