The Extraction of Paracetamol (the active ingredient in the medication)
• To test the purity
• To calculate yield
This method can be used to analyse different paracetamol brands and calculate which one contains the greatest quantity of the active ingredient.
There are two stages to the experiment; extraction and melting point determination.
Equipment for the extraction stage:
2 paracetamol tablets
20cm³ propanone
25cm³ measuring cylinder
2X 100cm³ conical flask
Warm water bath
Filter funnel
Filter paper
Glass funnel
Evaporating basin
Accurate scales
Goggles, lab coat, gloves
Method for the extraction stage:
1. Using accurate scales, record the mass of two paracetamol tablets.
This step must

2. Next break both the paracetamol tables in half (this speeds up the process of them breaking down) and add to a conical flask with the propanone and leave in a warm water bath (set to 40 degrees Celsius) until the tablets have broken down.
Breaking up the paracetamol tablets before putting them in the flask speeds up the process of them breaking down. The paracetamol tablets and propanone are heated in the hot water bath to allow the reaction to occur.
When we carried out this step we found that the tablets took much longer to break down than we expected, I would have to bear this in mind if the experiment had to be carried out again e.g. for repeats. The water bath should be set to 40 degrees Celsius – too high could damage the flask and alter the composition of the paracetamol and too low would result in the paracetamol taking a very long to break up, if at all.
3. Swirl the flask occasionally to aid the breaking up of the tablets and speed up the
Attention: The commercial grabs the viewers’ attention because the viewer will want to know which product works faster to remove unwanted stains. It also uses music and a little humor.
Louise C. Cope et al, investigated the impact of non-medical prescribing. Non-medical prescribing could be evaluated through the NMP, or other health practitioner such as GP, and patients. Currently there is limited information on how NMP has impacted other professions, such as radiographer, optometrists and physiotherapists. Personally, I think this is due to how recent these professions gained the right to prescribe. Most of the findings have been extremely positive, with limited disadvantages. Within this evaluation of NMP “students who are becoming NMPs felt that the programme provided them with adequate knowledge to prescribe with some stating that the period of learning in practice was ‘the most valuable part of the course’”
Paragraph 2: It is believed that as the temperature of the water increases the time it will take for the tablet to dissolve will decrease. This is believed since the temperature there will be more energy allowing the particles to get together and form a reaction allowing the ta...
Use a stopwatch or timer to determine the amount of time it takes for the tablet to completely stop fizzing out or until it completely stops dissolving.
5.) One at a time, place your test tubes in the water bath and heat the first test tube to 25 , the second to 50 , the third to 75, and the last to 100 degrees c. Remeber to stir with your stirring rod every so often.
the ones that contains ppt in half, then add 6M NH3 to one set of them
4. Pour about 300mL of tap water into the beaker. Set up a hot-water bath using a hot plate, retort stand, and thermometer clamp. Alternatively, use a Bunsen burner, retort stand, ring clamp, thermometer clamp, and wire gauze.
In the article titled, Why the $600 EpiPen Costs $69 in Britain by James Paton and Naomi Kresge depicts the overwhelming increase in the price of the lifesaving medical device in the United States. The EpiPen’s prices are comparable to the new iPhone 7 in the U.S. while it would only less than a leather case in Britain. In the article, an advocacy group was able to report that it is still a profitable business when being sold at lower prices. Take a look at Europe’s model for drug pricing compared to the U.S. In the U.K., the government and the pharmaceutical industry negotiate on the spending limits on health services. If a pharmaceutical company exceeds that negotiated cap, they must repay the government for their over expenditures. While in the U.S. they had some sort of
Acetaminophen is ingested orally and is rapidly and completely absorbed into the gastrointestinal tract. It works in about one hour. The liver detoxifies 90% of it by mixing it with sulfuric acid, and another 3-5% is catabolized by enzyme reactions to the acid. The metabolites are excreted in the urine.
You have been asked to design an oral liquid formulation of ibuprofen for paediatric use.
Add 5 g crushed nutmeg and 50 mL hexane-isopropanol into a flask and warm for 15 minutes.
2. Step 2: Heat the mixture: Make sure the agarose dissolves. Wait until it boils and when you are going to transfer the mixture, wear gloves to avoid getting burnt. Transfer the mixture to a removable gel tray. 3.
In a 250ml beaker place 100mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved. After 1 minute measure the temperature and record it, do this for a further 2 minutes (3 minutes in total). Repeat this process for a total of 10 teaspoons.
Tylenol Case Study The discipline of public relations is a modern profession which has been in existence for only close to a century; however, it has already taken an important role in the fields of business, government, entertainment and non-profit organizations including educational institutions and healthcare organizations. Public relations professionals are required to have excellent organizational, interpersonal, and communication skills and have the ability to persuade the public. It is imperative for PR professionals to effectively communicate with the public in order to establish and maintain a positive relationship. Furthermore, public relations professionals must have the ability to work under pressure and effectively manage crisis, which may have a detrimental effect on the company and the public it serves.
Normal water will not do because of the impurities in it. · Methyl Orange indicator - The colour of this indicates when the sodium hydroxide has been neutralised by the hydrochloric acid. · Conical Flask - This is used to react the aspirin tablets with the sodium hydroxide. It is more appropriate to use as the shape of it makes it less likely that any should spill out. · Burette - This is used to add the hydrochloric acid to the sodium hydroxide.
