State five ways of softening hard water and plz explain
Answers
hi here is your answer - Answer:1] Ion-Exchange Water Softening - salt based ion exchange water softeners are the main form of water softener used for domestic household water supplies. They work by removing hardness-causing calcium and magnesium ions from the water and replacing them with sodium or potassium ions that coat the resin beads in the ion-exchange tank.
2] Salt-Free Water Conditioning: Template Assisted Crystallization / Nucleation Assisted Crystallization
This form of water conditioning is relatively new in commercial usage, and is now available at domestic household scale. The technology has been proven in controlled tests undertaken by the University of Arizona to reduce lime-scale production in hard water by over 96%.
3]Salt-Free Water Conditioning: Reverse Osmosis
Reverse osmosis is a process of forcing water through a series of extremely fine filters under pressure, in order to filter all impurities out of the water, down to molecular level.
4] Salt-Free Water Conditioning: Chelation
Chelation is a means of conditioning hardness-causing ions in water so they do not combine with other chemicals in the water to form so-called lime-scale. This process has been used for treating water in commercial applications for several decades, such as in factories, laundries and restaurants, but has only fairly recently become available for domestic scale uses.
5] Use baking soda in your cooking water
hope it helps.
