I need Help writing the net Ionic equation for the following formations !
And answering my questions for lab

2.) write a net ionic equation for the following of each precipitate with known cations .

3A.) write from most to least soluble

3c.) is this the order in the periodic table ?

Ba'' Ca pot was town separate short of paper: Do the following on a 2. a net ionic equation for the formation of each precipitate with the known are Remember that the cations are in solution as nitrate salts (e g brrium and these net ionic equalico (review ndo G and yuur graded Electrolytes lab repartk Number reactions based on the sumber in the previous table, and list them

Explanation / Answer

2.) Ba(NO3)2+H2SO4=BaSO4+2HNO3

( Ba+2+2NO3-+2H++SO42-=BaSO4+2H++2NO3-)

Thus net ionic reaction is Ba+2+SO42-=BaSO4 ( H+ and NO3- are cancelled out from left and right side.)

Similarly other net ionic reactions are

Ba2++CO32-=BaCO3

Ba+2+C2O42-=BaC2O4

Ba+2+CrO42-=BaCrO4

Ca+2+SO42-=CaSO4

Ca+2+CO32-=CaCO3

Ca+2+C2O42-=CaC2O4

Ca+2+CrO42-=CaCrO4

Mg+2+SO42-=MgSO4

Mg+2+CO32-=MgCO3

Mg+2+C2O42-=MgC2O4

Mg+2+CrO42-=MgCrO4

Sr+2+SO42-=SrSO4

Sr+2+CO32-=SrCO3

Sr+2+C2O42-=SrC2O4

Sr+2+CrO42-=SrCrO4

3. A) Solubility order is MgSO4>CaSO4>SrSO4>BaSO4 ie Mg2+(magnesium)>Ca2+(calcium)>Sr2+(strontium)>Ba2+(barium)

This solubility order is due to the decrease of solvation energy of cations from magnesium to barium at the same time increase of lattice energy from calcium salt to barium salt

3. C) This order is in periodic table. In the alkaline earth metal(ie group 2)
