Drinking too much water can lead to hyponatremia‚ water intoxication‚ water poisoning and death Liquid H2O is the sine qua non of life. Making up about 66 percent of the human body‚ water runs through the blood‚ inhabits the cells‚ and lurks in the spaces between. At every moment water escapes the body through sweat‚ urination‚ defecation or exhaled breath‚ among other routes. Replacing these lost stores is essential but rehydration can be overdone. There is such a thing as a fatal water overdose.

My findings in the assumptions around bottle water and tap water resulted in a wide range of how the water supply is regulated. There are two different agencies that regulate the water supply in the United States. The Food and Drug Administration (FDA) regulates bottled water. The Environmental Protection Agency (EPA) regulates tap water. Both agencies are highly regulated agencies and have different standards of how the water is delivered to the consumer. The FDA manufacturing process is

DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even
