The Biological Structure of Water Water is a substance with the chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Its structure enables it to carry out many important functions in the body. Water molecules are charged‚ with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. These opposite charges attract each other‚ forming hydrogen bonds. These are weak‚ long distance bonds that are very common and

Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

Does Adding Salt to Water Make it Boil at a Higher Temperature? Project Design Plan Everyone knows that water boils at 212°F‚ but does adding salt to a pot of water make it boil at a higher temperature? Being a person that cooks frequently at home‚ I wanted to test the debated idea that adding salt to my water will make it boil faster. One of my friends says it does raise the temperature and therefore cooks it faster. My other friend says it only helps it taste better. Literature

Introduction Water is necessary to life but it can be unhealthy too. In general‚ the water quality is poor in developing countries like Kenya. Water is a vector of diseases like yellow fever‚ diarrhea… Water purification is very important in these countries but people don’t have a lot of time to spare‚ they work or they are in the field and in general women must spend a significant amount of time walking to collect water. So we need to find a quick‚ easy‚ and economic solution that is as simple

The polarity of water Polarity means that the molecule has both a positively and negatively charged end. More important‚ the polarity of water is responsible for effectively dissolving other polar molecules‚ such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions. This is important to remember because for most biological reactions to occur‚ the reactants must be dissolved in water. Because water is able to dissolve so many common substances‚ it is known as
