Answer:
See explanation
Explanation:
The reduction potential of Cr III is more negative than that of NH4+ hence NH4+ will be displaced by Cr III from a solution of its salt according to the following reaction equation;
Cr2(SO4)3 + 2(NH4)3PO4--------->2CrPO4 + 3(NH4)2(SO4)
Hence;
A reaction occurs when aqueous solutions of chromium(III) sulfate and ammonium phosphate are combined.
