Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...
[9] [10] Some pool test kits designed for use by homeowners do not distinguish free chlorine and chloramines, which can be misleading and lead to non-optimal levels of chloramines in the pool water. [11] There is also evidence that exposure to chloramine can contribute to respiratory problems, including asthma, among swimmers. [12]

Devarda's alloy (Copper/Aluminium/Zinc) is a reducing agent.When reacted with nitrate in sodium hydroxide solution, ammonia is liberated. The ammonia formed may be detected by its characteristic odor, and by damp red litmus paper's turning blue, signalling that it is an alkali — very few gases other than ammonia evolved from wet chemistry are alkaline.
In recent years, the chemistry set has been re-imagined as a self-study kit, typically offering students better equipment and more explanatory tutorial content. For example, Thames & Kosmos offers a range of CHEM series chemistry sets targeting older children, culminating in the C3000 Kit, which includes a 172-page manual describing 387 ...
Rumours of the origin of urine indicator-dye go back at least as far as 1958, [1] and the story is commonly told to children by parents who do not want them to urinate in the pool. [3] A 1985 biography of Orson Welles describes him using such a dye as part of a prank in 1937.
Salter Science was a brand of science kits sold by Thomas Salter Ltd., a Scotland-based company which manufactured toys and science activity kits for children. [1] Kits included activities with electricity, microscopy, magnetism and crystal gardens, but the company is probably best known for their chemistry sets. The company also produced other ...
