Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as calcium and magnesium .
Moreover, because the acidic or basic drain cleaners themselves are washed down the drain, this contributes to pollution in the water supply. Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats.
Sugarelly, Spanish water, or liquorice water, is a traditional British soft drink made with liquorice that was popular in Scotland in the early to mid-20th century. [ 1 ] [ 2 ] [ 3 ] It could not usually be bought as such, but instead was prepared by leaving several strands of liquorice to diffuse in water for a period of time before drinking.
Made of liquorice, sugar, coconut, aniseed jelly, fruit flavourings, and gelatine, they were first produced in Sheffield, England, by Geo. Bassett & Co Ltd. Allsorts are produced by many companies around the world, but are most popular in Europe, especially Britain and the Netherlands, where they are called Engelse drop, meaning English liquorice.
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
Various liquorice sweets are sold in the United Kingdom, such as liquorice allsorts. Dutch, German and Nordic liquorice typically contains ammonium chloride instead of sodium chloride, prominently so in salty liquorice, which carries a salty rather than sweet flavour. The essential ingredients of black liquorice confectionery are liquorice ...
In the 18th century liquorice was used as a medicine both for humans and for horses. The Pontefract cake "was almost certainly a black cake, the portable lozenge used to make 'liquorish water', stamped with the castle lodge emblem of Pontefract to signify quality.
Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs . If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus ...
