Acid gas

solutions are mixtures of at least two chemicals which counteract the effect of acids and alkalis. Therefore, when a small quantity of alkali or acid solution is added the pH of the enzyme doesn’t change. To make the buffer solution you need 0.2 mol dm-3 of Na2HPO4 and 0.1mol dm-3 of citric acid this will give 100cm3 of buffer. Here is how to get the different pH in the buffer solutions: pH Na2HPO4 cm3 citric acid cm3 3 20.55 79.45 5 51.50 48.50 6 63.15 36.85 7 82.35 17.65 8 97.25 2.75 9 Apparatus

Enzyme Lab Report Hydrogen peroxide is a toxic byproduct of cellular functions. To maintain hydrogen peroxide levels the catalase enzyme deconstructs hydrogen peroxide and reconstructs the reactants into oxygen gas and water. The catalase enzyme is found inside cells of most plants and animals. Regulating the levels of hydrogen peroxide is crucial in homeostasis and analyzing it’s optimal conditions for performance is just as important. To understand the optimal environment for this enzyme, they

information have been given about water and pH levels. Water with it polar covalent molecules has many significant properties: hydrogen bonding, cohesion, adhesion, surface tension and heat vaporization. In the others hand, students also learnt about pH, acid and base as well as how to define them in term of properties and in pH measurement. During the experiment participants test properties of different pH solution and their affect to environment as well as the use of buffer in different solution. Methods:

optimum would be at a pH is 7, due to the liver, where catalase usually resides, being neutral. The experiment consists of introducing the catalase to hydrogen peroxide, after exposure to certain solutions; hydrogen peroxide, water and hydrochloric acids, all containing the adjusted pH, and measuring the height of froth formed, an observable representation of the activity of the enzyme. The final data indicated that

How to Be Successful at Composting As an avid gardener and as someone who is conscientious of my environment, I purchased a compost bin several years ago. I have an abundance of yard and lawn clippings that I am not willing to dump into our already stressed landfills. In turn, my efforts for composting benefit me greatly because I can use this finished material to improve my soil texture, the soil's ability to hold water, and as a fertilizer. Composting is a biological process for converting organic

Introduction Pool water sanitation is the process of maintaining and keeping the clarity, pH and chlorine levels of water constant by adding certain chemicals and structures. This is also to prevent unwanted waterborne diseases from growing in the water and spreading. Chlorine and pH levels are extremely important for having a healthy pool. They are not clearly linked, but they do affect one another. Cleaning and maintaining pools have much more depth to the dreadful chore than you may see on television

Introduction: Within a cell, enzymes are used as a catalyst to increase the rate of chemical reaction. They do not consume themselves, rather they help in increasing the rate of reaction. Within the body, enzymes vary depending on their specific functions. For instance, hydrogen peroxide is a toxic chemical, but it breaks down into harmless oxygen and water. This reaction can be sped up using the enzyme catalyst produced by yeast. Hydrogen peroxide is produced as a byproduct in cellular reaction

Pool Operations Pool Operator, Records and Plans The pool operator has appropriate training for maintaining and operating the pool. In addition, the operator was also the only caretaker of the pool and was knowledgeable and active with the pool safety plan and pool records. To illustrate this, the operator knew where the safety equipment were located in the pool area; how to balance and maintain the pool water; and performed the regular maintenance and cleaning of the pool. Also, the Fraser Health

Since the neutralization reaction yields H2CO3, it's decomposition would produce carbon dioxide gas, which would bubble out of the solution. The neutralized solution was placed back into the funnel and the aqueous layer drained; after this washes with 10 mL of concentrated brine and 10 mL distilled water were performed to remove the NaCl and water

pH level, substrate concentration, and salt concentration. In these experiments, Catalase will be placed in different conditions with hydrogen peroxide. How active the enzyme is in these different conditions will be measured by the amount of oxygen gas being produced. A very high increase in oxygen will indicate a high reaction rate and a low production of oxygen will show that there is a low reaction rate. On the other hand, if there is no change in the level of oxygen, it will indicate that the
