3. Sodium hydrogen carbonate was added to the solution until it becomes neutral. Ph paper was used for this test to determine its ph value. 4. The reducing sugar test were carried out again as in section A(i). Results: Solution observation Before After Sucrose Colourless Brick red Test for starch

need to become hardened and strong. The Industrial Revolution was ultimately when man made fossil fuels became a problem for the environment. Before it, about 98% of Earth’s coral reefs were surrounded by waters with adequate aragonite saturation stats, which helped them maintain a healthy ecosystem (Oceana, 2014). However, now almost 60% of coral reefs are in waters that have less adequate aragonite saturated stats (Oceana, 2014), meaning that maintaining their hardened exterior has become increasingly

a soft drink created around 1886, is quickly booming into one of the most recognizable brands in the world. It has spawned dozens of different flavors and merchandise. However, it is a highly acidic substance, with a whopping 2.52 on the pH scale. The lower the pH number, the higher the acidity. This is because of the acids that make up the drink, such as phosphoric acid, added to give a tart flavor and thickness (or viscosity) to the drink. Tylenol is a brand of acetaminophen that they used for

creates an atmosphere that is immensely concentrated in CO2; therefore, the ocean absorbs more of the CO2 in the air. According to Marah Hardt and Carl Safina from Yale Climate Connections, high concentrates of carbon dioxide in the ocean creates a PH balance that is very low causing the ocean to become very acidic. When carbon

It is lipid-soluble, practically insoluble in water at low pH and freely soluble in water at high pH. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8 (43). 3.1.1.2. Pharmacodynamics Pharmacotherapeutic group: non-steroidal anti-inflammatory and antirheumatic drug, propionic acid derivatives, ATC code: M01AE02. Naproxen is a non-steroidal

the reaction faster. Reaction: In this experiment, the change of pH was also a key step of the reaction because the pH factors in the stability of an enzyme. Since we used an enzyme in this reaction, the pH levels of the solution needed to change first before adding the Horseradish peroxidase Type 1. The reason for changing the pH levels is to ensure that the enzyme will work during the reaction and having a high or extreme pH causes the denature an enzyme. After 0.50 grams of Vanillin were dissolved

an explanation of water within the body, the location and the function of five electrolytes that are found within the body and the importance of maintaining this balance. I am finally going to include how the three buffer systems help to control the pH within the body. Distribution of

Acid Rain: its Effect Acid rain refers to precipitation that is more acidic (having lower pH levels) than average. In more detail, acid rain is a type of precipitation that has mixtures of wet and dry materials coming from the atmosphere, which includes more nitric and sulphuric acids (Conserve Energy Future: Acid Rain). Acid rain can also be written as “Acid Deposition” because the acid rain could come down as other precipitation, for instance, snow. This became a worldwide problem due to the

Geography is "the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these"(oxford dictionary). This essay will assess the relevance of pollution in a geographical context. Pollution is any substance that enters a new environment which has harmful effects. This then therefore has an effect on the local environment, but also the consequences will be felt socio-economically. As a consequence, it is also a huge political issue. Pollution

Observation: The enzyme catalase naturally existing in yeast reacts with H2O2 to create oxygen and water, causing a yeast soaked paper to float after a certain amount of time. Problem/Info: Enzymes are large protein structures, also known as macromolecules and catalysts. They aid in the acceleration of chemical reactions by binding to another substance known as a substrate, converting it into different products that are more easily broken down called products. Only a small portion of the enzyme
