From the above equations it can be seen that 2 moles of thiosulfate is equivalent to 70.9 grams (2.50 ounces) of active chlorine. Again the percentage of available chlorine can be calculated through the concept of normality. The gram equivalent of bleaching powder is equal to the gram equivalent of the standard titrant used.
It is very common in blogs and websites to incorrectly name a specific connector only by the name of the manufacturer. To minimize confusion, it is best to describe a connector using: the manufacturer's name, exact connector series, and optionally the pitch, such as "JST-XH" or "JST-XH-2.50mm" or "2.50mm JST XH-series" or other variations.
The pilot pin is located in the centre of main contact circle on 4- and 5-pin connectors. On 3-pin (2P+E) connectors, it is located on the contact circle opposite the ground pin. The other connectors are located 105° on either side of the earth pin, rather than 120° as in the smaller variants, to make room for the pilot pin.
[2] [3] The many types are partly to prevent incorrect connection. [2] The larger connector sizes are the most varied, with designated connectors ranging from analog and digital signals to AC and DC power. [4] Each "coding" has a different keyway that prevents incorrect connection between incompatibly keyed connectors. [5]
Weak chlorine solution" is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite granules. [48] "Dakin's Solution" is a disinfectant solution containing a low concentration of sodium hypochlorite and some boric acid or sodium bicarbonate to stabilize the pH. It is effective with NaOCl ...
The hypochlorite anion and chlorine are in equilibrium in water; the position of the equilibrium is pH dependent and low pH (acidic) favors chlorine, [11] Cl 2 + H 2 O ⇌ 2H + + Cl − + ClO −. A hypochlorite bleach can react violently with hydrogen peroxide and produce oxygen gas: H 2 O 2 (aq) + NaOCl (aq) → NaCl (aq) + H 2 O(l) + O 2 (g)
Sodium hypochlorite solution, 3–6%, (common household bleach) is typically diluted for safe use when disinfecting surfaces and when used to treat drinking water. [31] [32] A weak solution of 2% household bleach in warm water is typical for sanitizing smooth surfaces before the brewing of beer or wine. [citation needed]
Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
