BRIAN M. Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion.

KMno4 can be prepared from K2MnO4 as per the reaction : 3MnO2−4+2H2O⇌2MnO−4+MnO2+4OH−. The reaction can go to completion by removing OH− ions by adding -

Potassium has one electron in its outer shell, and Sulfur has two. When forming an ionic compound with one atom of sulfur, two potassium atoms are used. ... This is an ionic bond and is the basis of the ionic compound formed, as the differently charged ions are held together by their opposite charges.

A typical analysis of kieserite reveals 15.0% magnesium (25% as magnesium oxide, 75% as magnesium sulfate), 20.0% sulfur (as sulphate), up to 2.5% chlorides, and 12% water. When not stored in closed containers, specimens of kieserite will absorb water from the air and be converted to magnesium sulfate heptahydrate.

BaSO4 has Ba2+ and So4 2-. If the salt is composed of highly charged ions, it is insoluble in water. Anhydrous form of MgSO4 is hygroscopic and thus highly soluble in water. MgSO4 is composed f relatively low charged ions and thus it is very soluble in water.

In a solution H2SO4 splits in 2 H+ and a SO42- particle = 3 particles per mole. So 2 moles of H2SO4 will result in 3*2 = 6 moles of molecules (or, as in this case they are charged: ions).

In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 ammonium ions to balance the one -2 sulfate ion. This will make the formula for Ammonium Sulfate (NH4)2SO4 .

For acidification of KMnO4 solution, only H2SO4 is suitable whereas the other mineral acids like HCl and HNO3 are not. HCl is not used because some of the KMnO4 will oxidize chloride ions to chlorine gas.

One of which is ammonium nitrite (NH4NO2). The answer stated by the review is NH2O which doesn't make sense to me since I am assuming this is an ionic bond between two polyatomic ions. Another example was sodium sulfate (Na2SO4) where the answer was Na2SO4.
