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

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