CuMnO4 is an ionic chemical compound (a metallic salt) known as copper (I) permanganate, or cuprous permanganate.
MnO4- is known as the permanganate ion. For the record, copper (II) permanganate (cupric permanganate) has the similar chemical formula Cu(MnO4)2.
The balanced equation for CuMnO4 + K3PO4 would be: CuMnO4 + 2K3PO4 → Cu3(PO4)2 + 3KMnO4 So, the set of coefficients that would balance this equation is 1:2:1:3.
The reaction between Cu3(PO4)2 and KMnO4 would likely result in the formation of CuSO4, MnO2, and K3PO4 as the products. The manganese in KMnO4 would be reduced from +7 to +4 oxidation state, leading to the formation of MnO2. The copper ions from Cu3(PO4)2 would likely form copper(II) sulfate (CuSO4), while potassium phosphate (K3PO4) would also be formed.
The reaction of copper and silver nitrate produces copper(II) nitrate and silver. This involves the displacement of copper by silver in the reaction. The balanced chemical equation for this reaction is: Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag.
