amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte solution.

Fluoride is a substance that is put in water and many other things to prevent oral problems‚ such as diseases‚ cavities‚ and decay. The way fluoride works is water fluoridation. Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay and various oral conditions. There is a price to adding fluoride to public water . Typically fluoridation‚ in the U.S. costs an average of about $1 per person-year . Fluoridated water has fluoride at a level that is effective

Journey to the Ocean Floor Oceanography is a science that draws upon the methods and knowledge of geology‚ chemistry‚ physics‚ and biology to study the ocean. The Pacific Ocean is the largest and the deepest ocean. Most submersible dives follow a similar pattern‚ emphasizing bottom transecting‚ collecting and photographing specimens. To understand our ocean floor exploration‚ you must first know something about the ocean floor. Follow along below as I summarize the parts of the ocean floor.

Water is determined by the amounts and kind of suspended and dissolved substances in the water‚ degree of alkalinity (pH)‚ temperature‚ colour and smell‚ and the company of undesirable microorganisms. In this experiment‚ we are explaining whether bottled water is more pure than tap water. For this experiment‚ hypothesis is which water is more pure bottled or taps water. To test the experiment we have used the equipment like bottled water‚ tap water and water test kit. In the research‚ it has been
