Discussion In this experiment, the chemical reaction between acetone (CH3COCH3) and iodine (I2) to make CH3COCH2I, I-, and H+ was observed. Under normal circumstances, this reaction would occur very slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable…

Aim: • To investigate the effects of on the rate of reaction of magnesium with different concentrations of Hydrochloric acid (HCl). • To investigate the effects of different surface areas of magnesium in its rate of reaction with hydrochloric acid (HCl). Introduction: The rate in which reactions occur between chemicals, such as Magnesium and Hydrochloric Acid, are effected by four main factors. These factors are temperature, concentration, the presence of a catalyst and the surface area of…

Evaluating the benefits and problems associated with malolactic fermentation of Merlot wines Emma Bruwer, 16122364, BSc Agric (Viticulture and Oenology), J.H Neethling Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch. August 2015 ABSTRACT Malolactic fermentation is the conversion of harsh and acidic malic acid to a more desirable form of lactic acid in wine by Lactic acid bacteria, after the completion of alcoholic…

solution, making the water more basic. Moreover, this type of water refers to its pH level, which is a number that measures how alkaline a substance is on a scale of 0-14. For example, if something will have a pH level of 1, it will be very acidic. On the other hand, if it has a pH of 13, than it will be very alkaline. Several experts believe that this type of water can neutralize the acid in your body, because its pH level is higher than regular drinking water. For example,…

Discussion Fold purification was calculated from specific activity. From sample A to B there was the addition of MgCl2 which denatured some proteins that were removed in the pellet. The second step of purification was even more successful with a 4.1 fold increase in purification, it was achieved by denaturing the non-recombinant E.Coli proteins. The Second step was much more beneficial to the total purification but the combination of the two steps achieved an even better purification of 4.6…

tree, it can influence the growth, injury, and death of an entire forest (epa.gov, 1). Someone with little knowledge on this topic might ask, “how can rain even damage a tree so badly to point where it dies”. Well, because acidic rain has a pH of about 2 ( pH levels can be judged on a scale from 0 to 14, where 0 is considered most acidic, therefore placing acidic rain to be very acidic; comparable to lemon juice) it can break apart the protective coating on leaves which leaves them injured and…

industrial revolution our climate has changed drastically. Industrial waste is now a necessary problem that collides with our daily life. This lifestyle can be too much for the fragile ecosystems our world holds. The rise of ocean acidification lowers the Ph level, which kills the coral that holds some of the most beautiful life. The Scientist who researched Ocean Acidification left a great understanding to how carbon works with the sea. These studies…

or something the Coral Reefs? They are beautiful aren’t they? That is why we cannot let them die off because of Acidification. Acidification is when too much carbon dioxide gets into the ocean which increases the acidity of the water and lowering the ph. I know other issues may be talked about more but if we look really close at acidification, acidification is a huge aftermath of those issues. I swear the human species as a whole is so transparent in the sense that we only see what we want to…

Normal pH within the blood can range between 7.35 and 7.45 arterial and venous is 7.32 thru 7.42. Normal HCO3 for arterial is 22 thru 26 mEq/liter and venous is 19 to 25 mEq/liter with PCO2 normal for arterial 35 thru 45 mm Hg and venous 38 thru 52 mm Hg. Normal PO2 is 80 to 100mm Hg for arterial and venous is 28 thru 48 mm Hg. Acidosis can affect the central nervous system within the body and left untreated can lead to death. Alkalosis affects the central nervous system which can cause muscle…

Most aquarists that have an irregular pH would rather use a natural means of balancing the pH of salt water because of the beneficial effects on, not only the overall water chemistry, but the non-lethal effects on the waters inhabitants. A very common pH balancer is crushed coral, which is a chemical mixture of solid aragonite. Aragonite is a polymorph of calcium carbonate, and a natural pH buffer. Crushed coral could quite possibly be the solution for reversing…
