All forms of botulism can be fatal and are considered medical emergencies. Foodborne botulism is a public health emergency because many people can be poisoned by eating a contaminated food. What kind of germ is Clostridium botulinum? Clostridium botulinum is the name of a group of bacteria. They can be found in soil.
The flasks were thoroughly cleaned with distilled water. 3. Samples of the Ammonium Persulfate ((NH4)2S2O8), Potassium Iodide (KI), Ammonium Sulfate ((NH4)2S2O4), Potassium Nitrate (KNO3), Sodium Thiosulfate (Na2S2O3), and Starch were placed in separate Erlenmeyer flasks. 4. Each flask was labeled according to its content (i.e.
Add a quarter spatula of copper (II) oxide and warm the solution gently to the 4th test tube and record observations. 7. To the 5th test tube, add 3cm3 of ethanol a couple of drops of conc, sulphuric acid and warm gently. Pour the resulting mixture into 30cm3 of sodium carbonate solution to remove excess acid and smell and record observations. Experiment 2 Time | Observations | 5 minutes | Bubbled like sugar | Once salt water was added | Turned soapy white and thick | Equation: METHOD 1) Put 2 cm3 of castor oil into a 250 cm3 beaker and add 10 cm3 of 5mol.dm-3 sodium hydroxide from a measuring cylinder.
With your fingertips, pinch the sides together of the empty pipette labeled HCl. 13. Gently tip the 24-well plate towards you so that the drops of HCl are puddled together along the bottom rim. Insert the stem of the pipette into the puddle and release the pressure of your fingers to suck all of the HCl into the pipette. 14.
It can be caused by raw meat coming in contact with already prepared food or unwashed food, and undercooked food. The main cause of salmonella is coming in contact with feces from a person or animal. As gross as this sounds it does happen due to people not washing their hands, thus causing salmonella to enter the body and go into the intestines and that is where it lives until killed. It is a very small bacteria that cannot be seen by the human eye just by microscope. Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands.
Put aspirin powder in a beaker and pipette exactly 30 cm3 of a 1 M NaOH solution onto the powder. Stir the beaker in order to dissolve aspirin completely. 3. Add 3 drops of phenolphthalein to the beaker with aspirin powder and NaOH solution. NaOH solution would be in excess and thus prepare 1 M of HNO3 solution in burette, which will be used in back-titration.
Calculate the molarity of the original vinegar solution and its concentration in gdm-3, given that it reacts with NaOH in a 1:1 ratio. 7. 2.5 g of a sample of ethanedioic acid, H2C2O4.nH2O, was dissolved in water and the solution made up to 250 cm3. This solution was placed in a burette and 15.8 cm3 were required to neutralise 25 cm3 of 0.1 moldm-3 NaOH. Given that ethanedioic acid reacts with NaOH
Speaking for myself, I would stop eating that food if I knew there was mercury in it, because I care about my body, I know mercury is poisonous, etc, etc, I could go on with a list of reasons as to why I personally would not eat food with mercury in it. I could make a long list about how much recycling would help our environment, or how if everybody was a vegetarian the O-zone wouldn’t be nearly as damaged. The problem with this question “Is Indifference Corrosive?” is that it’s unique to each individual person. In order to be indifferent to begin with, the receiver of the information must assess the information given to them and then the receiver must ask a multitude of questions such as: Will caring about this issue affect me positively or negatively? Will caring affect me at all?
For example, tomatoes are injected with fish gene to make a new product with better quality because the components in fish can protect fruit from freezing. Nevertheless, this matter can cause a serious consequence for people who get allergic with fish. Hence, labeling will allow consumers to identify and steer clear of food products that could cause them problems. Last but not least, labeling GM foods
