* Water is a natural resource of the utmost importance; nothing on earth can survive without it. Aside from drinking‚ water is used for agriculture‚ cooking‚ bathing‚ cleaning‚ industrial purposes and sanitation. When the demand for water exceeds its supply for an extended period of time‚ scientists refer to the situation as water stress. This serious issue leads to lower quantity and quality of freshwater resources. While most causes are human-related‚ others are uncontrollable. Population Growth

diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If

Investigating Stoichiometry with Carbonic Acid Salts Problem: Testing the actual yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation

Water treatment * Water treatment - describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water‚ industry‚ medical and many other uses. Such processes may be contrasted with small-scale water sterilization practiced by campers and other people in wilderness areas. The goal of all water treatment process is to remove existing contaminants in the water‚ or reduce the concentration of such contaminants so the water

Professor Family and Consumer Sciences Important for Life W ater makes up approximately twothirds of the body’s weight and approximately 75 percent of the brain’s weight. Nearly 4 percent of the water in the body is lost through the skin‚ lungs and through urine and stools each day. This water loss must be replaced continually by beverage and food consumption. Sweating causes greater water loss and increases the need to consume

Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe.
