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 .
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.
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 and fittings.
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.
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.
By 1780 liquorice growing was concentrated almost wholly in Pontefract and in Surrey, around Godalming. In Pontefract the growing of liquorice was done on plots of land behind people's houses. In a map of the 1648 Siege of Pontefract (reproduced by Chartres [ 3 ] ) the liquorice is indicated as being grown in "garths" either side of Micklegate ...
It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent, builder, lubricant, food additive, stain remover, and degreaser. [7] As an item of commerce TSP is often partially hydrated and may range from anhydrous Na 3 PO 4 to the dodecahydrate Na 3 PO 4 ·12H 2 O. Most ...
Industrial uses are many and varied, including: Vapor de-greasing solvent; Refrigerant and heat-transfer fluid; Anhydrous fluid cleaner; They are sometimes applied as blends such as HFE 7100, which is a mixture of methyl nonafluorobutyl ether (methoxyperfluorobutane) and methyl nonafluoroisobutyl ether.
