first aide- move victim to fresh air, administer o2, remove all contaminated clothing, if in contact with eyes flush for 20min and wash the skin with soap and water. Immediately cool burned areas with warm water and don't remove any clothing stuck to the skin. Carbon monoxide- gas toxic and flammable. Extremely toxic when inhaled or absorbed though the skin. Isolate area for 100 meters in all directions.
While the vinegar passed through the soil leaving more dirty water. Based on what I think, vinegar is saturated and a natural substance while oil is a man made product and a much thicker substance. Oil absorbed the soil leaving the water less contaminated. My conclusion, vinegar was the more potent liquid. Using at least 1 scholarly source, discuss what type of affects these contaminants (oil, vinegar, detergent) might have on a town’s water source and the people who drank the water?
The different kinds of Aspirin tablets are: * Enteric Coated Tablets * Capsules * Regular Tablets * Dissolving Tablets. Each tablet will be dissolves in both Water and Hydrochloric Acid (representing saliva and stomach acid respectively). Hypothesis The Enteric Coated tablet will remain undissolved in both water and Hydrochloric Acid as the coating is designed to remain undissolved until reaching the small intestine. The dissolving tablet will dissolve the fastest in both water and Hydrochloric Acid as this tablet is designed to quickly dissolve in liquid. The capsule will soften but not completely dissolve in the water, however will dissolve in the Hydrochloric Acid.
B: Ingestion of an acidifying drug in this case is to blame. With the introduction of Topamax to Mary’s system, the Topamax begins to inhibit her renal carbonic anhydrase causing metabolic acidosis. 9. B: IV of HCO3- in isotonic solution is the best option and my recommendation. Even with the carbonic anhydrase being inhibited and causing metabolic acidosis, direct injection
When pH is high which means more OH⁻, then aluminum ions will react with hydroxide ions to form aluminum hydroxide. Phosphate ions are acting as a natural buffer. If the equipment is not washed with acid, it would cause an error. This is because the phosphorus analyzing is dealing with low concentration of phosphorus and it is easily contaminated by detergent and other chemicals and it has to be washed by using an acid and also it has to be rinsed with distilled water once it is rinsed with acid. Also refer to section 4 (discussion).
h) A way to make hard water softer is to put an sodium nitrate and create a precipitate to mellow out the reaction. Another way of making it softer is by removing the calcium ions one way of doing that is by boiling the solution to take out some of the ions. Conclusion: Overall, we determined that sodium carbonate, Na2CO3, is the anion that can be used to precipitate the most metal cations. Also, we learned that the anion sodium chloride, NaCl, could be used to remove silver ions from solutions. The stuff that I found interesting was that how many colours you can get when you mix the cations and anions
The aspirator was turned to medium high, and then the copper was poured onto wetted filter paper. Using distilled water to remove all copper from the beaker. Once completely on filter paper 6mL of acetone was added to the copper to help dry it out. The filter paper was then removed and set down to dry completely. Once dry the filter paper was weighed with the copper on it and subtracted from the original weight to see the amount of copper left after
To keep the colors from fading, washing the fabric and drying it is good, but the key ingredient is soda ash. You sprinkle soda ash into a tub of water and let your fabric soak for a minute or two. The soda ash will lock in your dye and make your colors more vibrant and they will be less likely to fade. You can find soda ash in most craft stores. The amount of soda ash to use varies so it is a good idea to read the directions before adding it.
Add the HCl SLOWLY to the magnesium by running it down the side of the beaker. Adding the acid too quickly will result in the spattering of the acid. Write down any observations of the reaction. 6. After all the acid has been completely added and the reaction has stopped, use a pipette to add a few extra drops of acid into the beaker until the reaction stops.
The used acetate solutions are mixed with phosphate buffer which is followed by mixing with chloroform solution, than again with phosphate buffer and then with ether solution. Acidity should be neutralized to prevent any further hydrolysis. Penicillin in ether solution is mixed with with sodium bicarbonate. As a result of this mixing penicillin-sodium salt is obtained that can be stored as a stable powder at room temperature. The penicillin-sodium salt is obtained from the liquid material by basket centrifugation, in which solids are easily removed.
