experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble the titration and stockpot‚ use

Percent of Water in a Compound CHEM 1315-022 For experiment one‚ The Determination of the Percent of Water in a Compound‚ the sole purpose of conducting this experiment was to determine the percent of water found in compounds such as Magnesium Sulfate‚ Copper Sulfate‚ and so on. Along with determining the percentages of the hygroscopic compounds the experiment allowed for the exploration of separation of hydrogen bonds to ionic solids through the use of heat. The reason that the water clings to

There are several genera of micro-organisms related to contact lens storage case contamination. Unlike CL contamination which is bacterial in nature‚ storage case contamination is often polymicrobial.(Larkin et al. 1990; Gray et al. 1995) Gray et al found that bacterial contamination is common in 77% of lens cases‚ followed by contamination with fungi (24%) and then protozoan (20%). Most commonly found organisms include Pseudomonas aeruginosa‚ Staphylococcus spp‚ Acanthamoeba spp and Fusarium species

following Aβ-injection [19]. 2.5. Behavioral test: Morris water maze (MVM) 2.5.1. Apparatus The Morris water maze test was conducted as described [20‚ 21]. The maze consisted of a circular pool (200 cm in diameter) filled with water (23±2°C) to a depth of 40cm. The circular pool divided into four arbitrary quadrants. A transparent Plexiglas platform (the only escapable thing from the water) 10cm in diameter was submerged 2cm underneath the water surface at the midpoint of one quadrant. There were many

needs water to survive. Water is our most important resource that is required to ensure our survival. This resource is something that we use every day in our lives and it serves many different purposes. We use water to take showers‚ to flush the toilet‚ cook dinner‚ to drink‚ and to clean. Water is not only used for our domestic needs‚ or wants but it is used in agriculture‚ industries‚ transportation‚ and as an alternative energy source (Lenntech‚ 2008). Life would be impossible without water. All

of purified water again. Due to the people of the United States drinking billions of gallons of water daily‚ the amount of purified water we drink is starting to run out which is causing a problem already. Psychological studies have shown humans still don’t accept water being reused even after knowing the water is purified and perfectly clean. Advocates are still against ultraviolet machines being used to clean and purify water. While some people believe that drinking recycled water is both repulsive
