Question

name these ionic compounds: compound name cahpo₃ 0 mg(h₂po₃)₂ 0 mg(hco₃)₂ 0

Explanation:

Step1: Identify cations and anions for $CaHPO_3$

Calcium ($Ca^{2 +}$) is the cation, and $HPO_3^{2 -}$ (hydrogen phosphite) is the anion. So it's calcium hydrogen phosphite.

Step2: Identify cations and anions for $Mg(H_2PO_3)_2$

Magnesium ($Mg^{2+}$) is the cation, and $H_2PO_3^-$ (dihydrogen phosphite) is the anion. So it's magnesium dihydrogen phosphite.

Step3: Identify cations and anions for $Mg(HCO_3)_2$

Magnesium ($Mg^{2+}$) is the cation, and $HCO_3^-$ (bicarbonate or hydrogen carbonate) is the anion. So it's magnesium bicarbonate or magnesium hydrogen carbonate.

Answer:

compound	name
$Mg(H_2PO_3)_2$	magnesium dihydrogen phosphite
$Mg(HCO_3)_2$	magnesium bicarbonate (or magnesium hydrogen carbonate)
