I was going to make fun of you for not knowing how to write properly, but I"m guessing Russian is your first language.

A major goal of this course is the development of effective technical writing skills. To help you become an accomplished writer, you will prepare several research papers based upon the studies completed in lab. Our research papers are not typical "lab reports." In a teaching lab a lab report might be nothing more than answers to a set of questions. Such an assignment hardly represents the kind of writing you might be doing in your eventual career. Written and oral communications skills are probably the most universal qualities sought by graduate and professional schools as well as by employers. You alone are responsible for developing such skills to a high level. http://www.essayplanet.org/

How to write talumpati?

That s a very good start. What could the indicator be contaminated with? It could have something else in it that adds a different color (for instance, a trace of red dye in phenolphthalein indicator would make the color change go from pink (very light red) to. well, pinker. Tough to see!) Or, it could have something in it that would interfere with the reaction - maybe by adding extra acid or extra base. The systematic error will always be in the same "direction". all your results will be too high or too low, and generally by the same amount. For the random error: If you hold the test tube too high or too low, your reading will be too low or too high. You re not always going to hold it at exactly the same wrong height, so sometimes you ll be too high and sometimes too low, there s no pattern to it. For rinsing the test tube - this probably depends a lot on exactly what you did during the experiment, and I can t guess that from the hints provided. If you don t rinse out the test tube thoroughly between uses, then some of your solution will actually be whatever was in there last. (For instance, if your test tube held acid first, and you didn t rinse it out, and then added 5 mL of base. the acid that was left neutralized a tiny bit of the base. If you pour out that solution, and add another 5 mL of base - the stuff that was left in there the second time was already basic, so it didn t neutralize anything; the second solution was more basic than the first, but the difference isn t really repeatable enough to count as "systematic" error.)
