Question
In your soap synthesis added a solution of sodium chloride and then cooled the reaction mixture in order to make the soap precipitate. How does adding the salt help the soap to precipitate? The reason is less obvious in this case since it is based on intermolecular forces. The soap is an organic anion is solvated in water because it is a hydrogen-bond acceptor Adding a large amount to sodium chloride salt results in stronger water solvation by chloride compared to the soap anion, watch decreases solvation of the soap anion and helps it precipitate. Give a brief explanation for why the condo anion is a stronger hydrogen-bond acceptor than the soap anion. This is a fairly important phenomenon to molecular biology. It is called 'salting out", where adding salt to water helps to precipitate DMA. proteins etc. What is hard water and why is this an issue when using sop? Why is the Salt River, that runs through Tempe so-called?Explanation / Answer
12) Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when waterpercolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. Water hardness is a source of many problems. One important trouble area is the way hardness minerals react with soaps and detergents.The list of elements that possess this property of hardness include iron, copper and manganese, all present normally in relatively small quantities. More common, of course, are calcium and magnesium, which are usually present in significant amounts. Clothes washed in zero soft water are free of troublesome hard water soap curd.
13) Tempe Town Lake is a reservoir that occupies a portion of the dry riverbed of the Salt River as it passes through the city of Tempe,
11) The chloride anion is a stronger hydrogen bond acceptor than soap anion because Chloride anion is lewis acid which is very strong acid and accepts stronger hydrogen bonds.
