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.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
The hydrates of the salts lose water at different temperatures during decomposition. [12] For example, in the trihydrate MgCO 3 ·3H 2 O, which molecular formula may be written as Mg(HCO 3)(OH)·2H 2 O, the dehydration steps occur at 157 °C and 179 °C as follows: [12] Mg(HCO 3)(OH)·2(H 2 O) → Mg(HCO 3)(OH)·(H 2 O) + H 2 O at 157 °C
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
2 CH 3 COOH + Mg(OH) 2 → (CH 3 COO) 2 Mg + 2 H 2 O. Magnesium carbonate suspended in distilled water with 20% acetic acid solution. [8] 2 CH 3 COOH + MgCO 3 → Mg(CH 3 COO) 2 + CO 2 + H 2 O. Reacting metallic magnesium with acetic acid dissolved in dry benzene causes magnesium acetate to form along with the release of hydrogen gas. [9] Mg ...

Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
Magnesium gluconate is a compound with formula MgC 12 H 22 O 14.It is the magnesium salt of gluconic acid.. According to one study, magnesium gluconate showed the highest level [dubious – discuss] of bioavailability of any magnesium salt which implies its viability as a supplement, although of the 10 salts studied, all increased magnesium levels significantly.
