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

The Water Cycle * Name three important needs of water. a. Almost all of the body’s living cells need and depend on water to perform their functions. b. Water carries nutritive elements to the cells and carries away waste materials and salts to the kidneys. c. Water serves as an important constituent of lubricants. * How is water distributed through the biosphere About 97 percent of all water is in the oceans. Three percent of all Earth’s water that is freshwater. The majority‚ about 69

SALT WATER Introduction: Salt water refers to water that contains dissolved salts‚ known as saline water or seawater‚ water from oceans or seas. It is a home to varieties of aquatic animals‚ for example‚ fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean‚ sea‚ and coral reefs

Introduction: Water is an essential living source for us humans and has a big impact on our everyday lives‚ thus people should be very concerned about what is actually in our tap water that we drink from everyday. The fluoride in the water can either occur naturally or by adding fluorine‚ by drinking a certain amount of fluoridated water each day can help to prevent tooth decay; the fluoridated water works on the surfaces of our teeth and causes the fluoride level in our saliva and hence reduces

really felt like water was ever an issue in my life‚ right up until I wrote the wrong essay for class last week. It all started when the teacher mentioned that he drank over 5‚000 water bottles per year or so. After that day I started paying attention to how much water I drink and how basically all the water I drink comes from water bottles that I keep buying through out the day. Hydration is a big deal‚ especially in the heat we have to bear living in San Antonio. I drink at least 5 water bottles per

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

drinking water samples from different places using four of the standard drinking water tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan
