ACKNOWLEDGEMENT

I feel proud to present my Investigatory project in Chemistry on the topic “Sterilization of Water using Bleaching powder” which aims at using Bleaching powder as a disinfectant and purifier to make water fit for drinking.

This project wouldn’t have been feasible without the proper and rigorous guidance of my Chemistry teacher Mrs. Mohini Belani who guided me throughout this project in every possible way. An investigatory project involves various difficult lab experiments which have to be carried out by the student to obtain the observations and conclude the report on a meaningful note. These experiments are very critical and in the case of failure, may result in disastrous consequences. Thereby, I

    Although not all water can be used for drinking purposes, in many places, water that is drinkable- is polluted or deluded by many agricultural and industrial motives and damage humans have caused (Friend). In this experiment, the goal is not to purify muddy water completely from microorganisms and bacteria, but to find the most efficient way to cleanse it from the dirt and soil particles that cause the murky color using physical…

    (3) Citric acid is a colourless fruit acid. It is obtained directly from citrus fruits but can also be produced biotechnically. In system cleaning, the citric acid in AquaStar 1 is used for natural and effective descaling of the drinking water system (the water heater in particular). The descaling effect is achieved by a combination of the acid and the formation of a calcium complex. The advantage of using citric acid instead of vinegar for cleaning drinking water systems is the avoidance of the unpleasant vinegary taste. Citric acid also affords better corrosion protection to stainless steel containers by removing free iron from their surfaces.…

    2. The Rf values were not recorded in lab. However, spot results were recorded. The TLC plates 1-3 showed the presence of starting material (SM) in the crude product (CP) lane. TLC plate 1 was taken after adding the initial addition of 0.25mL of bleach. TLC plate 2 was taken after adding an additional 0.08mL of bleach because plate 1 still showed presence of SM in the CP lane. TLC plate 3 was taken after adding an additional 1mL of bleach for the same reason. However, TLC plate 4 did not show any SM in the CP lane and this was after adding an additional 3mL of bleach. The plate only showed a CP spot, indicating that the reaction had gone to completion.…

    As the group number decreases, reactivity increases. As the period increases, the most reactive is towards the bottom. The alkali metals (Group 1 metals) are identified as the most reactive of all present elements on the periodic table. Seeing as potassium and sodium are both found in group 1, this will suggest that potassium will be the most reactive metal. Additionally, potassium should be more reactive than sodium as its single valence electron is placed more distant from the nucleus than sodium, meaning less energy is needed to remove the valence electron, therefore meaning the reactivity is higher.…

    Water is determined by the amounts and kind of suspended and dissolved substances in the water, degree of alkalinity (pH), temperature, colour and smell, and the company of undesirable microorganisms. In this experiment, we are explaining whether bottled water is more pure than tap water. For this experiment, hypothesis is which water is more pure bottled or taps water. To test the experiment we have used the equipment like bottled water, tap water and water test kit. In the research, it has been noted that tap water is more pure than bottled water.…

    First thing is to make your hypothesis on how to filter dirty water like mine “My hypothesis is if I use one cut bottle and layer it to be pebbles, sand, cloth, charcoal, then cloth, sand, and pebbles it filter the water will be cleaned.”. Then you start to build hypothesis, so start by getting a bottle, cut the bottom of the bottle like two inches of it. You take the cap off the bottle then get two coffee filter and use two rubber bands to tie it to the cap of the bottom. Then add about a inch of pebbles of to the bottle, and then about a half inch layer of sand, a layer of cheesecloth. Next is a layer of charcoal, layer of cheesecloth, then a half layer of sand, finally a layer one inch pebbles. Your hypothesis is made, but it is not time…

    The advantages of using bleach as a disinfectant is strong and effective disinfectant. Its active ingredient, sodium hypochlorite, denatures protein in micro-organisms and is therefore effective in killing bacteria, fungus, and viruses. Household bleach works quickly and is widely available at a low cost. The disadvantage is could irritates mucous membranes, the skin, and the airway. It also decomposes under heat or light and reacts readily with other chemicals. Bleach solutions begin to lose its effectiveness after 2 hours. You will need to make a fresh solution for each experiment.…

    Water is one of the many things that all human being need in order to survive. Considering the vast amount of water that is on the planet, it is reasonable to believe that there is more than enough water for everyone to have their fair share and more. Yet this sadly is not the case, as the majority of the water on Earth is unsuitable to drink due to the fact that it is tainted with a numerous amount of contaminants, such as bacteria and salt. The amount of safe drinking water is decreasing more and more each year and will soon become one of the more scarce resources on the planet. Over the years, many different people all over the world have tried to create and refine a water purification process that is both effective and efficient. The…

    Background: According to the Millennium Development Goals Report 2012, 783 million people, or 11 per cent of the global population, remain without access to an improved source of drinking water. Also the United Nations has long been addressing the global crisis caused by insufficient water supply to satisfy basic human needs and growing demands on the world’s water resources to meet human, commercial and agricultural needs (un.org). In this experiment water quality and contamination of groundwater was investigated. First, I observed the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the large amount of contamination in the water, while the laundry detergent will just create an aroma smell to it. Considering the smells and color to these ingredients I think that it will cause the water quality to have a bad smell and cause the water to be very cloudy. Once filtering the contaminated water, the water will be clear and purified. Second, I will experiment water treatment and filtering. I predict that once the contaminated water is treated and filtered that it will leave me with less contamination or none at all. Then for the last experiment, I will determine the difference between bottled water and tap water to discover any contamination. I predict that the tap water will be the most contaminated and with the most chemicals in it, while the bottled waters; Dasani and Fiji will be completely filtered and free of any chemicals.…
