  2. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3 −, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [5] It is a source of nitrogen, and nitrogen was named ...

  3. Potassium nitrite - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrite

    Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2. It is an ionic salt of potassium ions K + and nitrite ions NO 2 −, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. [1] It is a strong oxidizer and may accelerate the combustion of ...

  4. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

  5. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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 ...

  6. Ionic strength - Wikipedia

    en.wikipedia.org/wiki/Ionic_strength

    Ionic strength. The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts.

  7. Alkali metal nitrate - Wikipedia

    en.wikipedia.org/wiki/Alkali_Metal_Nitrate

    Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO. The melting point of the alkali metal ...

  8. Golden rain demonstration - Wikipedia

    en.wikipedia.org/wiki/Golden_rain_demonstration

    Golden rain demonstration. Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead (II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain ...

  9. Niter - Wikipedia

    en.wikipedia.org/wiki/Niter

    Niter or nitre [5] is the mineral form of potassium nitrate, KNO 3.It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term niter was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions.
