Solutions & Solubility
Pure water, which is an odourless, colorless, and tasteless substance is often called the universal solvent. As water moves through soil, it dissolves very small amounts of minerals such as calcium and magnesium. The greater the content of calcium and magnesium, the more hard the water is. Therefore, hard water is the result of an excess of two elements, C and Mg. The hardness of water is measured in grains per gallon (gpg), milligrams per litre (mg/l) or parts per million (ppm). (See chart below)
Grains Per Gallon Miligrams
Per Liter (mg/l) or Parts Per
Million (ppm) Rating less than 1.0 less than 17.1 Soft
1.0 - 3.5 17.1 - 60 Slightly Hard
3.5 - 7.0 60 - 120 Moderately Hard
7.0 - 10.5 120 - 180 Hard over 10.5 over 180 Very Hard
You can also detect hard water in your home by examining it for any evidence of film left on your body, the build-up of scale on cooking utensils, clogged pipes, appliances resulting in reduced water flow and increased repairs high in dissolved minerals, specifically calcium and magnesium. Yet although hard water is a nuisance, it poses no health risks.
Some of the consequences of hard water include harsh and rough laundry, a film of sticky soap on the skin and faulty operation of water-using appliances such as clogged pipes. Furthermore, solar heating used for heating swimming pools could be prone to build-up that interferes with the electric pump. Although hard water may interfere with almost every cleaning task, it is still safe for drinking, cooking, and other household uses and may even add to the taste of water, providing a small amount of nutritional benefit.
Water softeners, however, may also increases the sodium content in the water, which may pose health concerns regarding a person’s intake of sodium. Some of the benefits of softened water include an increase in the life expectancy of the plumbing system, water-using appliances and a reduced soapy residue on clothes, skin, hair, tubs and shower tiles. It will also prevent the scratching of bathroom fixtures as well as sinks and decrease spotting and white chalky deposits, on dishes, pots and pans and glassware.
Since the minerals in water give it a characteristic taste, when water is softened it may taste salty and might not be suitable for drinking. Therefore, soft water may taste bad, but hard water may shorten the life of plumbing and lessen the effectiveness of certain cleaning substances.
There are two ways to help control water hardness, adding a packaged or liquid softener to a batch of water, or by using an ion exchange water-softening unit.
...instead of 25 years if they pleaded guilty. (Wan 37) In addition, money can become a reason for defense attorney to encourage pleading guilty. Private defense attorney may want to spend more effort in cases where they have more possibility of winning and thus getting more money, and public defenders find pleading guilty an effective way to move through cases quicker. (Mohr 6) For prosecutors, “guilty pleas avoided ‘onerous and protracted’ trials whose outcomes – ‘losing’ or ‘having to oppose an appeal to the higher courts’ – were both undesirable.” (Smith 134) Finally for judges, plea bargain reduces their caseload, and elevates their reputation indirectly because accepting a plea bargaining also includes waiver of appeal to higher courts. (Mohr 6)
There has been some speculation regarding if plea bargains are effective or not, in regards to obtaining a desirable outcome. Some thoughts are that plea bargains are used to scare innocent defendants into pleading guilty. Another theory is that guilty defendants use plea bargains just to expedite their sentencing. As said by Chin, because there is the possibility of an innocent defendant pleading guilty, this merits an obligation to lawyers ensuring that the client understands the consequences (Chin
The plea bargaining process agreement allows for both the defendant and prosecutor to dodge lengthy trails, as well as allowing for the defendant to escape the risk of a guilty verdict. Therefore, it is intentional the usage of plea bargains in order to leave defendants and the prosecutor better off; however, how better off are prosecutors and defendants truly?
Drinking water is one of our basic needs in order to survive, therefore the water that we drink and cook with must be of a high quality, and filtered of any harmful contaminants.

It tastes disgusting and it can give you so many problem with your body and your cells. It’ll make your kidneys not work which will probably eventually make your body fail. Your body can’t get rid of all that extra salt. It’s obviously better to drink fresh water because that will actually make your kidneys work. Salt is good for your body, but drinking too much salt water is really bad for you. Your blood can’t handle all the extra salt that comes with the sea water. The water in your cells has to go outside of itself to go balance all the salt. When a cell does that, it can start to shrink which is really bad for you. Salt water even just tastes horrible and with all the other effects, it’s not worth to drink salt
The Biological Importance of Water as a Solvent and as a Medium for Living Organisms
While purchasing a house also makes someone take up a massive financial debt (mortgage), renting does not and so, when one is in their youth, they prefer to rent than to buy simply because buying a house is not affordable. Likewise, there would be fewer maintenance expenses of renting in comparison to buying. When one is young, they prefer to travel and move around with respect to their job and renting enables one to do so; buying a house at one place would mean one cannot travel much farther for a job. Renting would also enable one to reduce opportunity costs and keep their liquidity for other prospects, in contrast to purchasing. All of the advantages of renting are disadvantages of purchasing/owning a house in
This is a review of the article The Marlboro Man: Cigarette Smoking and Masculinity in America, written by Michael E. Starr in 1984 for the Journal of Popular Culture. The article examines what factors were involved in diminishing the unmanly stigma associated with cigarette smoking in the twentieth century. The United States is the geographical focus. The time period ranges, but the bulk of the article deals with 1900 to 1970.
Water is the most important molecule that exists on the Earth. Without water living beings would not be able to live. Water is used for an immeasurable number of things. There are many properties of water, which makes this molecule so unique. One which people overlook is hardness. Hardness is defined in the Chemistry: The Central Science by Prentice Hall's as being "water that contains a relatively high concentration of Ca2+, Mg2+, and other divalent cations." Water containing these ions is not a health hazard; however, it is a problem for industries and households. Therefore, the hardness of water is vital to understand in order to prevent the problems it could cause.
...ed to clean much more effectively. Soft water is much gentler, but it can be criticized as being too “soft”. One is not particularly safer than the other, and it all comes down to a matter of opinion over which one should be used in the household.
Alkaline water is water that’s less acidic than your regular tap water. That generally means the water it is rich in alkalizing compounds such as calcium, silica, potassium, magnesium, and bicarbonate according to Ryan Adams for Precision Nutrition.
Water is more than something that we drink when we are thirsty or use to bath ourselves when we wish to be clean. Water makes up 71% of the Earth’s surface, being made of just two hydrogen atoms and one oxygen atom. It is vital for life to be sustained on Earth, allowing plants to survive and provide oxygen for animals to breathe and function while suppling animals with the core necessity that they need to strive towards survival. When we think of water, the first thing that comes to the minds of many is either in a glass or in a bottle, ready to be drank. When water is pure, it can usually be described as odorless and tasteless. Water samples may taste better than others. Due to water’s qualities of being an exceptional solvent, that being that water allows many compounds to be dissolved in it, this also water to carry the nutrients that ware vital to plant and animal health and even
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
When water contains a lot of calcium and magnesium, it is called hard water. Hard water is not suited for all purposes water is normally used for.
