The most common problem that a chemist faces is a measurement of different reactants. One has to know the exact concentration of reactive agents in a solution to be capable to use this reagent in further experiments. It will be an undesirable fallacy to consider that only chemists may be interested in the resolution of this problem. One can encounter this assignment even while writing an essay without direct connection with analytic chemistry, such as composing botany papers or an ecological dissertation. An acid-base titration technique is constantly used in industrial production and in monitoring of environmental objects. Therefore, a rigorous researcher ought to know primary principles of analytical chemistry in order to eschew possible obstacles. Among the most accurate and suitable methods of chemical analysis, we can separate the most often employed technique, which is, of course, an acid-base titration method. Titration is a volumetric method based on the gradual addition of a mixture with already known concentration (a standard solution) to the sample solution. This technique is founded on the exploration of the effects of the neutralization reaction. Scientists receive the result of the titration comparing the concentrations of the working mixtures at the concrete point, which is called an equivalence point, and the volume of wasted reagents.
This type of analytic reaction has many pluses and it keeps its place among the most popular methods of modern chemical investigation. Without going into specific details that can interest only specialists in narrow fields of chemical science, we can name the following advantages of the acid-base titration method:
Writing a report about the performed laboratory experiment may seem a quite sophisticated task, but you will probably not find it more complicated than composing short essay scholarships. The main requirements are still the same: accuracy, precision in the formulation of theses and perfectly accomplished calculations. Let us examine an example of laboratory report that may be helpful as the demonstration of basic principles of acid-base titration. During this assignment, you must perform standardization of strong acid, for example, hydrochloric acid, using a standard mixture of sodium carbonate. At first, wash the burette with the acid solution and fill it with a standard solution of hydrochloric acid. Drain the excess of acid from the burette. Measure three conical flasks of a sodium carbonate mixture. Pour a standard volume of water to each flask. Usually, 20 ml of water is enough. Then add 1-2 drops of methyl orange to each flask. Place the first flask under the burette that contains the mixture of hydrochloric acid. Then you have to titrate the solution. The procedure is completed when the solution changes its color from yellow to orange. Record the amount of the acid mixture that was spend on the titration with precision to 0.1 ml. Repeat the previous operation 2-3 times. Now, the experimental part of this task is over. You need to detect the average result and discover the concentration of the solution. The necessary computations are quite simple, but if you consider that you may need specific assistance with this part, you should ask for a help from specially designed services, just as you do with a maths coursework help. Remember, that calculations of the received results is an indispensable part of your assignment, so do not neglect this operation. Double-check all stages of your work, because your report must be written perfectly.
After accomplishing previous operations, you have to write a theoretical part of your report. A human mind has a regrettable feature to forget special knowledge if they were received only once. Repetition of the educational material will help you keep in mind all nuances of the experiment performed. Otherwise, you risk to lose the obtained experience. Therefore, your report should contain all necessary theoretical information about the fundamentals of acid-base titration. Try to write your paper without going into particularized issues. A cumbersome report will only distract your attention from significant facts. Check the examples of laboratory reports supplied by a college paper writing service, because it will let you to compare your work with standard models and fix all errors and inaccuracies before it is too late.
