It was observed that bottled water contained more impurities than tap water, and that water treatment reduced the amount of impurities in the water. It was concluded that tap water was a safe and cheap source of drinking water.
Water quality is a term that illustrates the state of water. It encompasses the chemical, physical, biological and radiological attributes, usually with respect to its suitability for a particular purpose (Diersing, 2009). Water is considered contaminated if it contains certain substances to the extent that makes the water unsuitable for a given purpose (Ofwa, 2013). Contaminated water may have an unpleasant coloration, smell, taste, turbidity, organic matter, unsafe chemical substances, deadly heavy metals among other harmful substances (Fawell & Chipman, 2000). Contamination of surface waters, ground waters or seawaters creates a serious risk to life particularly when the water is used by humans for drinking and other domestic purposes. Most pathogens that cause illnesses such as dysentery, cholera and typhoid are most often found in contaminated water (Ofwa, 2013). There are many negative effects of water contamination with each type of contaminant having a different effect on human/animal health and ecology.
The main objective of this lab practical was to examine the effect of contaminants on ground water quality, effectiveness of water treatment and purity of tap and bottled water. The first experiment sought to establish the effects of groundwater contamination while the second experiment looked at water treatment procedures and their effect on water safety. Conversely, the third experiment aimed at assessing the purity of three different types of drinking water (tap, Dasani® bottled and Fiji® bottled) in terms of chemical substances ...Download file to see next pages Read More

Organic Chemistry

The extraction of compounds from these natural products is an example of solid/ liquid extraction-the solid being the natural product and the liquid being the solvent into which the compounds are extracted. In research, a Soxhlet extractor is often used for solid/liquid extraction.
Although solid/liquid extraction is the most common technique for brewing beverages and isolating compounds from natural products, liquid/liquid extraction is a very common method used in the organic laboratory, specifically when isolating reaction products. Reactions are typically homogeneous liquid mixtures and can therefore be extracted with either an organic or aqueous solvent. Organic reactions often yield a number of by products-some inorgani...

These values also imply that the reaction is pseudo first order reaction.
(iv) A plot of rate of reaction (J) vs. concentration of AsO33- i.e.[A] was made (figure 2, below). A linear trendline was drawn using MS excel. Slope of this plot gives the rate constant. The value of the rate constant is 5.3x10-3s.
d) From data given in table (2) a plot of lnkR' vs. 1/T was made (figure 3, below). Slope of this curve equals -E/R, where E is activation energy of the reaction and R is the Universal gas constant, which equals 8.38 Jmol-1K-1.
Therefore, -E/R = 8122.6 K
Or, E = 8122.6*8.38 Jmol-1= 68067.4 Jmol-168.7 k Jmol-1
Q3. a) The mechanism in this case is SN1 i.e. Nucleophilic Substitution of First Order. In this mechanism...

...Introduction to Organic Chemistry Organic chemistry is a specific branch of chemistry, basing off of the study of the element carbon, and its relations to life and the world around it. Sometimes called “life” chemistry because of living things presence of carbon, organic chemistry includes reactions, formulas, and processes, are all based off of carbon chains and its unique properties. Carbon, the element used for most radioactive dating, contains specific properties that help is be on of the building blocks of life. There are various different groups and arrangements of the element carbon, all with their own different properties and structures. Carbon is often a key player in making organic compounds, and understanding...

Question 2-What is the effect of an insoluble impurity, such as sodium sulfate, on the observed melting point of a compound? Insoluble impurities, although very. undesirable, will not affect the melting point.
Question 3-Three test tubes, labeled A, B, and C, contain substances with approximately the same melting points. How could you prove the test tubes contain three different chemical compounds? Even if two different compounds have the same melting point, if they are mixed together the melting point of the mixture will be lowered because the compounds are no longer pure. You would take a sample from two of the compounds, X and Y, mix them. If the result of a lowered melting point is present, then the two are different co...

Building a Self-heating Cup: A Comparison of Two Exothermic Reactions Introduction Background Information A self-heating cup would allow you to heat food, coffee, or water without a stove, electricity, solar energy, or a flame. An exothermic reaction (usually, hydration of metal salts in water) provides the heat energy required. In the cup, the reactants are placed in separate compartments. A trigger on the cup allows you to heat the contents of the cup when required. On press of the trigger, the wall separating the reagents punctures and water reacts with the reagent to generate heat. An average self-heating cup can raise water temperature from 20°C to 80°C and sustain the temperature for 40 minutes (Bargan Production Group).

Applications and Development of Catalyst for the Synthesis of Highly Functional Organic Carbonates

The negative effects can also be minimized through production of synthetic polymers which are biodegradable or easy to recycle.
Carbon as important industrial raw material is predominantly sourced from fossil sources of energy while plastic synthesis accounts for about seven percent of oil usage in the whole world. The future of fossil energy is not promising and as such need for other routes like biorenewable energy sources and biodegradable polymers. The world is also producing around 150M tons of plastic per year, America alone carries the burden of 30M tons which in landfills or get incinerated on our soils per year. This increases need for easy to recycle and biologically degradable polymers; they are valuable as they pos...

For example, steel containing a higher percentage of Mn is suitable for production of complex tools and durable machine parts. Contrarily, steel containing a substantial percentage of chromium is used to produce metallic parts that resist corrosion. In this case, quantitative determination of transition elements in steel is significant in industrial chemistry.
Primarily, steel is made up of iron but it contain trace amounts of transition metals like manganese, chromium and copper among others. In practice, the actual amount of each element in a steel alloy can be determined quantitatively. This lab exercise covered on quantitative determination of manganese Mn in an unknown sample of steel. Determination of Mn in steel took ad...

cent concentration is high, Heating of luminescent substance or if it is exposed to infrared radiation or an electric field this results causes the probability of no radiative transitions. This process is usually undesirable and very high requirement are therefore imposed on the purity of luminescents.phosphors which rapid quenching of luminescence occurs when the temperature is raised or when it is exposed to infrared radiation are also used.
Varieties of molecular interactions can also result in quenching. Examples include excited-state reactions, molecular rearrangements, energy transfer, ground state complex formation and collisional quenching
Quenching can occur due to optical properties of the sample. High optical de...
