Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

Blank 1 Blankity Blank Blankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment‚ you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing

Environmental Effects of the Bottled Water Industry Environmental Science Environmental Effects of the Bottled Water Industry I myself am a firm believer in drinking only bottled water under the belief that it is safer‚ cleaner‚ and better tasting. I also believed that the bottled water industry couldn’t be polluting the environment. After all how could something so natural be bad for the environment? In the research that follows I will explain just how wrong I really was in my beliefs
