  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 a potassium salt of nitric acid.This salt consists of potassium cations K + and nitrate anions NO − 3, and is therefore an alkali metal nitrate.

  3. Potassium nitrate (data page) - Wikipedia

    Chronic Exposure: Under some circumstances methemoglobinemia occurs in individuals when the nitrate is converted by bacteria in the stomach to nitrite. Nausea, vomiting, dizziness, rapid heart beat, irregular breathing, convulsions, coma, and death can occur should this conversion take place.

  4. Ruthenium - Wikipedia

    en.wikipedia.org/wiki/Ruthenium

    Potassium perruthenate can also be produced by oxidising potassium ruthenate, K 2 RuO 4, with chlorine gas. The perruthenate ion is unstable and is reduced by water to form the orange ruthenate. Potassium ruthenate may be synthesized by reacting ruthenium metal with molten potassium hydroxide and potassium nitrate. [39]

  5. Alkali metal nitrate - Wikipedia

    en.wikipedia.org/wiki/Alkali_Metal_Nitrate

    sodium nitrate produces a yellow/orange color, potassium nitrate and rubidium nitrate produce violet colors, caesium nitrate produces an indigo color. In a general way, the emitted color progressively turns from the red to the violet in the visible spectrum of light when going down in the column of the alkaline metals in the periodic table of ...

  6. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge (which combines with anions to form salts). In nature, potassium occurs only in ionic salts.

    Nitrate is a polyatomic ion with the chemical formula NO ... sodium, potassium, calcium, and magnesium salts. ... Nitrate formation with elements of the periodic table:

  8. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

  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.
