The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Periodate (/ p ə ˈ r aɪ. ə d eɪ t / pə-RY-ə-dayt) is an anion composed of iodine and oxygen.It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7.

Magnesium oxalate is an organic compound comprising a magnesium cation with a 2+ charge bonded to an oxalate anion.It has the chemical formula MgC 2 O 4.Magnesium oxalate is a white solid that comes in two forms: an anhydrous form and a dihydrate form where two water molecules are complexed with the structure.
The compound appears to be highly unstable but can react with alkenes to give halogenated products. [ 7 ] Radical iodine oxide (IO), iodine dioxide (IO 2 ), collectively referred to as I x O y and iodine tetroxide ((I 2 O 4 ) all possess significant and interconnected atmospheric chemistry.
Treating the solution of different soluble magnesium salts with alkaline water induces the precipitation of the solid hydroxide Mg(OH) 2: Mg 2+ + 2 OH − → Mg(OH) 2. As Mg 2+ is the second most abundant cation present in seawater after Na +, it can be economically extracted directly from seawater by alkalinisation as described here above.
[Mg(H 2 O) 6] 2+ → [Mg(H 2 O) 5 (OH)] + + H 3 O + (decomposes in water) MgCl 2 ·nH 2 O → Mg(OH)Cl + HCl + (n-1)H 2 O (decomposes when heated) Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar.
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
