Question

Write the formulas of the compounds formed by Ba2+

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

Answer 1

#1

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

#2

`\\ \tt\bull\rightarrowtail Ba^(2+)+SiO_3^(2-)\longrightarrow BaSiO_3`

#3

`\\ \tt\bull\rightarrowtail Ba^(2+)+HSO^(4-)\longrightarrow Ba_4HSO_2`

#4

`\\ \tt\bull\rightarrowtail Ba^(2+)+PO_4^(3-)\longrightarrow Ba_3(PO_4)_2`
