Cr2(SO4)3(aq) + (NH4)2CO3(aq) → 

Cr2(SO4)3(aq) → 2 Cr3+(aq) + 3 SO42-(aq)

(NH4)2CO3(aq) → 2 NH4+(aq) + CO32-(aq)


Sulfates (SO42-) are soluble except those of Ca2+, Sr2+, Ba2+, Ag+, and Pb2+
Carbonates (CO32-) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+)
