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,…

in the burette was set up. The pH meter was used to monitor pH of the system when sodium hydroxide was being added. NaOH was added in an increment of 1ml until the pH of the solution reached 4.8. After the solution reached pH of 4.8, NaOH was added in increment of 0.1ml until the solution passed its equivalence point. NaOH was added in an increment of 1ml after equivalence point until there was an insignificant change in solution pH when titrant was added. Values of pH and titrant used were…

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…

those obtained using more orthodox techniques such as UV spectrometry and pH measurements. The experiment in Dr. Evans paper will replicated using the same measurements and techniques. This project is to serve as a proof of principle, showing that literature value can be replicated using a weaker magnet. The pH experiment will be used to illustrate the kinetic of the clock reaction. The concentration of the reactants and the pH of reacting mixture will be varied to determine their effect on the…

Introduction: Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have…

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…
