Salt substitutes are low-sodium table salt alternatives marketed to circumvent the risk of high blood pressure and cardiovascular disease associated with a high intake of sodium chloride while maintaining a similar taste.
 They usually contain mostly potassium chloride, whose toxicity is approximately equal to that of table salt in a healthy person (the LD is about 2.5 g/kg, or approximately 190 g for a person weighing 75 kg).
 Potassium lactate may also be used to reduce sodium levels in food products.
 It is commonly used in meat and poultry products.
 The recommended daily allowance of potassium is higher than that for sodium, yet a typical person consumes less potassium than sodium in a given day.
 Seaweed granules are also marketed as alternatives to salt.
A shotgun shell is a self-contained cartridge typically loaded with multiple metallic "shot", which are small, generally spherical projectiles.
 Traditionally lead was used, but increasingly steel, tungsten or bismuth shot has replaced lead, due to laws designed to protect the environment.
 A single, large projectile known as a shotgun slug can also be used, and numerous specialty rounds such as less-lethal rounds (e.g. beanbag rounds), flechette rounds, lead-dust rounds for door-breaching are also available.
 An old non-lethal shotgun load consisted of a shotgun shell loaded with rock salt, which could inflict very painful, but rarely deadly, wounds, and was therefore popular for scaring away trespassers.
Mixed oxidant solution is a kind of Disinfection which is used for disinfecting, sterilization and eliminating pathogenic microorganisms in water and in many other applications.
 Using Mixed oxidant solution for water disinfection, compared to other methods, such as sodium hypochlorite, Calcium hypochlorite, chlorine gas and ozonation has various benefits such as higher disinfecting power, stable residual chlorine in water, improved taste and odor, elimination of biofilm and safety.
 Mixed oxidant solution is produced from electrolysis of sodium chloride brine (sodium chloride) and it’s a mixture of disinfecting compounds.
 The main component of this product is chlorine and its derivatives (ClO, HClO and Cl solution).
 It also contains high amounts of chlorine dioxide (ClO) solution, dissolved ozone, hydrogen peroxide(HO) and oxygen.
 This is the reason for calling this solution mixed oxidant.
The chemical traffic light is the reaction of the changing in color of the solution which is also related to the blue bottle experiment.
 One of the early formulas consists of glucose, sodium hydroxide, indigo carmine, and water.
 Another formula consists of indigo carmine, dye, ascorbic acid (Vitamin C), sodium bicarbonate, sodium chloride, copper(II) sulfate, sodium hydroxide and water.
 By doing so, chemical waste and the level of corrosive chemicals is reduced.
 The amount of solid chemicals dissolved in the experiment could be reduced from 60 grams to 6 grams.
 And the pH could be lowered from 13 to 3 which is easier to neutralize the pH to 7 by adding baking soda before disposal.
 Also, it is safer and the reactions also occur faster and are easier to perform.
Halite ( or ), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (NaCl).
 Halite forms isometric crystals.
 The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of impurities.
 It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates.
The chloride ion is the anion (negatively charged ion) Cl.
 It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
 Chloride salts such as sodium chloride are often very soluble in water.
 It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.
 Less frequently, the word "chloride" may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded.
 For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion.
Ringer's lactate solution (RL), also known as sodium lactate solution and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water.
 It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure.
 It may also be used to treat metabolic acidosis in cases other than those caused by lactic acidosis and to wash the eye following a chemical burn.
 It is given by injection into a vein or applied to the affected area.
Sodium bisulfite (or sodium bisulphite) (sodium hydrogen sulfite) is a chemical compound with the chemical formula NaHSO.
 Sodium bisulfite is a food additive with E number E222.
 This salt of bisulfite can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water.
 Sodium bisulfite in contact with chlorine bleach (aqueous solution of sodium hypochlorite) will generate heat and form sodium bisulfate and sodium chloride.
Sodium chloride , also known as salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
 With molar masses of 22.99 and 35.45 g·mol, respectively, 100 g of NaCl contain 39.34 g Na and 60.66 g Cl.
 Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms.
 In the form of edible or table salt it is commonly used as a condiment and food preservative.
 Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses.
 A second major application of sodium chloride is de-icing of roadways in sub-freezing weather.
Sodium bisulfate, also known as sodium hydrogen sulfate, is the sodium salt of the bisulfate anion, with the molecular formula NaHSO.
 Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically either in the form of sodium hydroxide or sodium chloride.
 It is a dry granular product that can be safely shipped and stored.
 The anhydrous form is hygroscopic.
 Solutions of sodium bisulfate are acidic, with a 1M solution having a pH of around 1.
