Fruit-infused Water


Water is a chemical compound with chemical formula H2O, water in nature existed in difference forms such as liquid, solid, and gas. Water is the source of life for all living things, most the parts of our body consists of water. We can learn many interesting things about water from the hexagonal molecular structure of water that has been studied by several scientist, its function for the health of our body, the anomaly of water while the solid phase, and other properties of water that quite difficult to be understood not only for some people in general, but also for scientists. Water is one of the most studied materials on this earth.

As we know most of our body is composed of water. Even at the molecular level nearly 99% constituent of our body is water. But why do we still need water? Because much of fluid are lost and out of the body through urine, feces, sweat, and breathe. So that we need to replace fluid lost by maintaining fluid balance in our body so that it can perform its functions optimally, where the water hold a vital role in the metabolism of our body and plays a role in keeping our body temperature. In normal conditions, our body needs about 2-3 liters of water a day (+/- 8 glasses a day). This is actually not supported by scientific research. Because the actual needs of fluid supply for each person are vary, depending on activity, temperature, humidity, environmental conditions and other factors such as gender and age.

Currently there is an interesting and popular method to replace fluids in the body when we are tired of water we used to drink (plain water). We can replace it by drinking fruit-infused water. Fruit-infused water is one of the smart ways to replace fluids without excess sugar and calories. This method is able increase our daily needs of fluids and may hinder us from dehydration. How to make fruit-infused water is very easy, we just need to infuse some pieces of fruit to taste into the usual beverages we drink. After that all the flavor and nutrient of the fruit will we get. When a piece of fruit is added to water, the water will dissolve nutrients (Vitamin C), sweetness and antioxidants in the fruit. Attractive appearance, good and refreshing taste can be used as a substituent for soft drinks on the market that are generally less healthy for our body, because they contain artificial sweeteners and preservatives.   

Many recipes are available on several websites. It is quite interesting to note, they offer vary of taste and benefits. One of the highlights is the recipes of fruit-infused water with extra lemon wedges.  As we know lemon not only provides good taste but also a range of benefits. It can lower the risk of diseases such as cancer, heart disease, slow weight gain, prevent colds, and various other disease. Intake of food such as red meat, dairy products, and sugar tend to make the body more acidic. Citric acid contained in the lemon is also able to maintain the pH of our body system in order to remain the ideal pH range. The ideal pH is base on the range 7.35 to 7.45. In this pH range, our body system will run normally.

Vitamin C contained in lemon can improve the immune system, the absorption of iron, the complexion; helps detoxify and produce collagen; reduce skin blemishes; and prevent the formation of kidney stones. A study in the journal of clinical Biochemistry and nutrition which states that a diet rich in lemon can prevent and reduce weight gain and body fat. Consumption can also help to control blood sugar and insulin function. Other research in the journal of research in medical science discovered that orange peel extract can help prevent and reduce the oxidation of LDL (bad cholesterol). When oxidized, cholesterol is the free radical that can increase the risk of inflammation and cancer. 

What is Hard and Soft Water?

What is Hard and Soft Water?

Have you boil water using your regular pot and then one day you realize that the bottom of your pot covered by a brown colored slag? Where did this slag come from when you usually use clean, colorless and scentless water? Or maybe you have experienced while bathing or washing, the soap you use is difficult to lather. 

Should you know that around 60% of water on earth derived from ground water, and that the water we use has gone through a cycle called the water cycle (hydrologic cycle). During the cycle the water is in contact with rocks and soils containing lime which dissolved minerals. Based on the mineral content, water can be divided into hard and soft water. Hard water usually contains Ca2+ (calcium ion) and Mg2+ (magnesium ion). Another cause of the water hardness is the presence of other metal ions such as Fe2+ (ferrous ion), Sr2+ (Strontium), and Mn2+ (Manganese). Calcium in the water has the possibility to bond with bicarbonate (HCO3-), sulfate (SO42-), chloride (Cl-) and nitrate (NO3-). Meanwhile magnesium in the water has the possibility to bond with bicarbonate (HCO3-), sulfate (SO42-) and chloride (Cl-). The following equation shows the reaction of water hardness origins.

Another question may briefly appear in your mind, if this kind of water is a health hazard or not? Of course not, because magnesium and calcium are minerals needed by our body. Calcium ions are required in the growth of bones and teeth, so as to prevent osteoporosis. There also a research studies told that hard water can lower the risk of heart disease and mortality. Hard water is not dangerous because it contain ions that easily soluble in water. But at the high rate hard water can cause the water to become cloudy also bring some another problem.

The first problem is pipe or crane in your house will be more quickly blocked by the slag produced from mineral deposits contained in this hard water. It is also increasing the cost of heating water due to the slag emergence on the kettle or water heater. Problems in the hair and skin may also appear as it looking dull and dry. Hard water is also not good to wash, the Ca2+ and Mg2+ ions binds to carbohydrates on the residual acid soap and form deposits that are not foaming the soap as well as decreasing its ability to cleaning up.

To solve this problem, you need to know in advance what kind of hardness water in your home or neighborhood. Is that temporary hardness or permanent hardness, so you can determine the way out to overcome these problems.

Temporary hard water containing bicarbonate ions (HCO3-), or it may be containing calcium bicarbonate compounds (Ca(HCO3)2) and or magnesium bicarbonate (Mg(HCO3)2). Water containing ions or compounds can be removed by heating the water until the water is free from Ca2+ and Mg2+. By heating the compound, CaCO3 and MgCO3 will settle on the bottom of a kettle. The occur reaction is :

While the permanent hard water contains anion other than bicarbonate ions, such as Cl-, NO3- and SO42- ions. Because that hardness cannot be simply removed by heating, then to free the water from hardness must be done by chemical substance that can precipitate the ions contained in hard water as in the Lime-Soda Ash (Lime-Soda Softening) with the addition of lime (CaO), soda ash (Na2CO3) or can also through the addition of caustic soda (NaOH). Apart from a few examples of the process of softening hard water, there are many other ways that can be done.

Here are some simple tips you can do at home to overcome the problems of hard water.
  1. Boil water before use
  2. Adding lime, washing soda, or lemon juice to the water in the bath shelter. But this way will take a long time.
  3. Adding ammonia, borax, alkali or washing soda to the water used for washing.
  4. Use white vinegar on tile, glass, and cranes to help remove mineral deposits.
