Question

Write the formulas of the compounds formed by Cu2+

with the following anions:
NO2 , SiO32- , HSO4-, PO43-

Answer 1

#1

`\\ \tt\bull\rightarrowtail Cu^(2+)+NO_2\longrightarrow Cu(NO_2)_2`

#2

`\\ \tt\bull\rightarrowtail Cu^(2+)+SiO_3^(2-)\longrightarrow CuSiO_3`

#3

`\\ \tt\bull\rightarrowtail Cu^(2+)+HSO^(4-)\longrightarrow Cu_4HSO_2`

#4

`\\ \tt\bull\rightarrowtail Cu^(2+)+PO_4^(3-)\longrightarrow Cu_3(PO_4)_2`
