With this knowledge at hand, it is possible to identify and unknown compound through qualitative analysis. Materials and Methods: Part 1 Cation Tests: To begin the experiment, 6M NaOH was added to centrifuge tubes containing potassium, iron (III), zinc (II), copper (II), and cobalt (II) in the metal hydroxide test. Drops were added until a precipitate was observed and separating the cations into two groups, those that did and those that didn’t form precipitates, eliminating certain cations. Additional drops of NaOH were then added to test for any amphoteric cations. For those that tested negative, 15 M NH4OH was added in the ammonium hydroxide test to observe for the precipitate color which further separated the cations.
These tests allow us to tell us how well the kidneys are working. The kidneys have several important functions in the body, including eliminating waste products through the urine and regulating the body’s fluid balance. Precise and accurate measurements will be crucial when dealing with medicine doses when treating patients because even a tiny bit too much of a medicine can do the patient harm. This lab acted as a way for us to learn how to make precise measurements and the skills that we learned in this lab will be skills that will continue to use for the rest of our careers. Experimental Results: The attached data and results sheet contains the data collected in the laboratory.
ABSTRACT: The lab of “observations of chemical changes” was to observe the changes that occur in chemical reactions and attempt to interpret these changes. In these experiments it taught me how to interpret chemical reactions with acids and bases. Also, how one chemical can have many different reactions when combined with other chemicals and how to interpret each reaction as what it could mean. I discovered not only how to measure out a well-balanced chemical combination to receive a reaction but to know how to test for acids and bases using a few different methods. Other tests also included in this experiment were testing for Sodium Bicarbonate, and Starch.
To prevent poisoning in both adult and children use safety locks on all cabinets, store food and chemical products in separate areas, keep medications out of sight, teach children about poisonous substances, and discard all old or outdated medications. 3. First aid for swallowed poisons is to have victim lay down, give victim lots of clear liquids, treat for shock, and seek medical attention 4. First aid for inhaled poison is to call 911 and poison control center, put unresponsive victim in recovery
The health of RadiologicTechnologists and the patient are at risk when concerning X-rays because of the gamma radiation rays, yet X-rays are vital to finding out what the medical issue is. An Associates Degree is required to be a Radiologic Technician. The skills needed to obtain the job are the ability to order items in a defined format or according to set rules; active listening skills; good oral communication abilities, radiologic positioning aids and locators; knowledge of x-ray archiving systems and medical x-ray darkrooms and supplies; and being able to use hypodermic needles. I think I would be a good fit as a Radiologic Technician because I want to help those who are sick and in pain by finding out
If you are exposed to this chemical you can either go blind if it goes in your eyes or possibly die. Another example is the explosion symbol. This symbol shows that the chemical is conbustable, which mean it can explose under pressure or force. All the symbols have meanings, and they are all put there on purpose to give for warnings to everyone. If you see these symbols, be sure to be very careful.
Experiment 3: Copper Cycle Purpose Statement In the experiment 3, I need to synthesis a number of copper compounds and need to recover copper metal. Before I can synthesis a number of copper compounds and recover copper metal, I need to collect all the observation, physical properties and solutions through the copper cycle, after that I can synthesis a number of copper compound. When I can synthesis a number of compound I can recover copper metal by weighting an empty weighing bottle and solutions from above experiment (copper that I collect from the copper (I) compound experiment and copper cycle). Data Table Table 3.1: Reagents used in the copper cycle and in the preparation of copper (I) solids Reagent | Appearance | Volume (mL) or Mass (g) | Concentration (M) | Cu(NO3)2 | Light blue, transparent | 10.0 mL | 0.10 | NaOH | Clear (colourless), transparent | 20.0 mL | 2.00 | HCl | Clear (colourless), transparent | 40 drops ~ 1.3 mL | 6.00 | NH3 | Clear (colourless), transparent | 50 drops ~ 1.7 mL | 6.00 | H2SO4 | Clear (colourless), transparent | 15.0 mL | 1.50 | Zinc dust | Silver, solid, very thin layer, shiny | 0.14 g | N/A | Ethanol | Clear (colourless), transparent, odour (alcohol) | 5.0 mL | N/A | CuCl2 • 2H2O | Green,
Once a company’s drug has passed this part of the process by showing that the drug is helpful and safe (Consumer Reports Best Buy Drugs 1), they have to create a drug label. The label must include the following: the name of the drug, critical warnings, dosage information, instructions on how to take the medication, foods and drugs you should avoid while taking the medication, the approved use of the medication, contraindications, the side effects and symptoms of adverse reactions, and instructions on how to store it (Jasper). Once a drug is permitted and can be placed on the market, the company can then go back into the lab and test the drug for other uses. This is important since the companies cannot lawfully endorse a drug to doctors other than what it was approved for (Consumer Reports Best Buy Drugs
Lastly, we need to empower our inspectors to have the authority to stop production when a bad sample is detected. This needs to happen before a bottle neck, as well, to ensure we do not waste time remanufacturing an order. We also have many long-term goals to discuss. They go as follows: Testing of the new bottle needs to be done to ensure safety to the end-user. Meanwhile, we will use the old style bottles
