  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.

  4. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    The nitrate anion is the conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. [citation needed] This charge results from a combination formal charge in which each of the three oxygens carries a ...

  5. Calcium nitride - Wikipedia

    en.wikipedia.org/wiki/Calcium_nitride

    Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: [3] 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: [4] Ca 3 N 2 + 6 H 2 O → 3 Ca (OH) 2 + 2 NH 3. Like sodium oxide, calcium nitride absorbs ...

  6. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons ...

  7. Calcium nitrite - Wikipedia

    en.wikipedia.org/wiki/Calcium_nitrite

    Calcium nitrite is an inorganic compound with the chemical formula Ca (NO. 2) 2. In this compound, as in all nitrites, nitrogen is in a +3 oxidation state. It has many applications such as antifreeze, rust inhibitor of steel and wash heavy oil. [1]

  8. Nitrate test - Wikipedia

    en.wikipedia.org/wiki/Nitrate_test

    A common nitrate test, known as the brown ring test[2] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]

  9. Ionic radius - Wikipedia

    en.wikipedia.org/wiki/Ionic_radius

    v. t. e. Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
