    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,…

    blended potato. The blended potato mixture was strained and put into a centrifuge, the liquid that was in the centrifuge contained the enzyme and remained on ice. The enzyme was placed in test tubes that had varying levels of pH buffers, substrate concentrations and temperatures; the pH, substrate concentration and temperature were the three variables. The data showed that each variable contained an optimum level at which the enzyme was most effective. Intro: Enzymes are vital to the existence…

    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…

    22 tons per day. Scientist thought it was it good thing because it wasn't warming the planet but instead it's killing marine life and endangering them. The ocean water is losing pH since its process that keeps pH balanced it's fast enough. We keep putting more CO2 in the air and the ocean is taking it all in. Since the pH levels…

    changes color when a solution reaches a pH of around eight, or in other words the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The combination of a weak acid and a strong base would result in an endpoint that corresponds to the range of phenolphthalein indicator approximately a pH of eight. Image A…

    chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7, even unpolluted water will have an acidic pH level of 5.6 due to…

    on the pH of the milk. At certain pH value, positively charges and negatively charges of the casein will equal, so that the number of electrons equals to the number of protons. [1] Approximately pH 4.6 is the pH value that acid casein is precipitated and least soluble. In milk, which has a pH of about 6.6, the casein has a net negative charge and is quite stable. However, if there is addition acid adds to the milk, it decreases the pH of casein. Therefore, less casein precipitates when pH value…

    Background Research Enzymes are biological catalysts, they have optimum pH values and temperatures, their activity is greatest while in optimum. Enzymes are also proteins, if the shape of an enzyme changes, it would no longer work. Enzymes are substances that fasten the chemical reactions in the human body. Enzymes are proteins that make up shapes in order to allow smaller molecules to fit into them to increase the chemical reaction rate. Although enzymes are made by living thing, enzymes are…

    effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and Loomis, no date). Generally the enzymes in plants work best at a pH of around 5-7.…
