  2. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species which results in the creation of products with similar or identical bonding affiliations. [1] This reaction is represented by the general scheme: For more details about displacement reactions, go to single displacement reaction.

  3. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and sodium chloride are used. The simplified chemical reaction is: NaCl + H 2 O + energy → NaOCl + H 2 [citation needed] That is, energy is added to sodium chloride (table salt) in water, producing sodium hypochlorite and hydrogen gas.

  4. Sodium acetate - Wikipedia

    en.wikipedia.org/wiki/Sodium_acetate

    Sodium acetate is also used in heating pads, hand warmers, and hot ice. A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12][13] dissolving in their water of ...

  5. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Water-reactive substances[1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium. Some water-reactive substances are also ...

  6. 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 ...

  7. RICE chart - Wikipedia

    en.wikipedia.org/wiki/RICE_chart

    An ICE table or RICE box or RICE chart is a tabular system of keeping track of changing concentrations in an equilibrium reaction. ICE stands for initial, change, equilibrium. It is used in chemistry to keep track of the changes in amount of substance of the reactants and also organize a set of conditions that one wants to solve with. [ 1 ]

  8. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq).

  9. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions (cations) and negatively charged ions (anions), [ 1 ] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
