Water for Profit - Essay Example Sometimes a sense of urgency of solving this problem is lacking until it is too late to do anything and then suffer its adverse consequences causing untold misery and numerous unnecessary deaths. It used to be that water from any source is clean and safe to drink, whether from the spring, river, lake or artesian well. Prior to the advent of the Industrial Revolution, this was a case usually in most rural areas. But the rise of factories and urban centers occasioned by the Industrial Revolution forced many people to live in congested and confined areas with little or no regard to sanitation. Before Western medicine and scientific research took hold, epidemics were fairly common, most of them caused by dirty water that had water-borne diseases in it. A new paradigm must be pursued regarding water resources, that although it is renewable, it is a not inexhaustible resource. There are many instances and situations where there is plenty of water but none of it is drinkable due to pollution. This paper examines a modern phenomenon of water being sold for profit, an unthinkable situation even just a few decades ago. People no longer trust their tap water and resort to drinking supp osedly purified water in plastic bottles. Nobody can dispense with drinking water. The rise of big cities and urban centers is a sign of progress and development. These areas require modern methods of sewerage and the sewage system, together with piping potable water into homes and offices. In his book, author Peter H. Glieck lamented the war on tap water in favor of profits and big business to the utter detriment of ordinary people. Good public governance requires those in power to provide all the basic necessities in life, through utilities such as municipal water and electricity to power homes and businesses. Suddenly, public water fountains disappeared from most public areas and bottled water is

Crystal Violate activation of energy Lab Report Example | Topics and Well Written Essays - 500 words

Crystal Violate activation of energy - Lab Report Example This reaction is as below in a simplified form by abbreviating the crystal violets chemical formula as CV. The violet-colored CV+ reactant slowly faded to a colorless product as the reaction proceeded, following the typical behavior of any indicator. The colour change were be measured by a Vernier Colorimeter set at 565 nm of wavelength in assumption that absorbance is directly proportional to the concentration of crystal violet according to Beer’s law. The molar concentration of the sodium hydroxide, NaOH, solution was much greater than that of crystal violet. This ensured that the reaction, which is first order with respect to crystal violet, was first order overall throughout the practical experiment. The reactions were monitored at different temperatures, while maintaining the initial concentrations of the reactants the same for each of the trial. The effects of temperature change on the rate of reaction were observed and measured. Finally, the activation energy, Ea, for the reaction was calculated. In this lab Experiment the apparatus and materials used included Lab Quest , Lab Quest App Temperature Probe, Vernier Colorimeter, Temperature Probe, 5 plastic cuvettes, 0.10 M sodium hydroxide, NaOH, solution, 2.5 Ãâ€" 10–5 M crystal violet solution, 1 liter beaker, ice, watch with a second hand, two 10 mL graduated cylinders, two 100 mL beakers and 50 mL beaker. In this experiment, the procedure was as follow. The initial step involved obtaining and wearing goggles. This was followed by connecting the Colorimeter to Channel 1 of LabQuest and the Temperature Probe to Channel 2 of LabQuest and choosing New from the File menu. The next step involved changing the data-collection rate to 1 samples /second and the length to 200 seconds. The colorimeter was the calibrated and the calibration used for all the four trials in the done in the experiment. In calibrating the colorimeter, a blank was prepared by filling an
