ACID RAIN Acidified particulate matter in the atmosphere that is deposited by precipitation on to a surface‚ often eroding the surface away. This precipitation generally has a pH less than 5and some times much lower depending upon the concentration of acidic components. Acidic deposition principally by the pollutant gases such as sulphur dioxide (so2) and the nitrogen oxides cause acidic deposition. The burning of fossil fuels‚ such as coal‚ forms Sulphur dioxide. that contain high quantities of

For my project‚ I had to create my own acid-base indicator and find out what happens when it is placed in an acidic solution (vinegar) and a basic solution (dissolved baking soda). I chose my indicator to be a fruit because fruits can be very effective at determining how acidic or basic a substance is. My fruit was a blueberry‚ but I couldn’t use raw blueberries because it’s not going to give me the best results. I had to make blueberry juice. I did this by placing several blueberries in a blender

How Healthy is the Conodoguinet Creek? Acid rain and Eutrophication are the two main pollution in Central Pennsylvania. Acid rain is a bad type of rain whiles eutrophication is the process where water bodies receive excess nutrients. Our mission here is to determine whether the Conodoguinet Creek is polluted or not. My hypothesis before the experiments was if there was to be signs of acid rain and eutrophication‚ then it means the Creek is polluted We went to the creek

Introduction: Acid rain increases the rate of corrosion on statues made of certain material. The town council wants to build a statue that will not be affected by acid rain. In this experiment‚ three different types of rock are used on vinegar (acting as acid rain). The rocks used are marble‚ granite‚ and red sandstone‚ which are the most popular forms of rocks used to build monuments. Each type of rock will be submerged under 20 ml of vinegar in their own separate container. The pH of acid rain around

reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

Exploring the acid content of Pepsi products Lab performed: February 27‚ 2012‚ March 12‚ 2012‚ and March 19‚ 2012 Purpose: The purpose of this experiment was to discover the unknown concentration of acid in six different Pepsi products; Pepsi‚ Diet Pepsi‚ Dr. Pepper‚ Diet Dr. Pepper‚ Pepsi Wild Cherry‚ and Pepsi Max. Titrations find the point at which equal moles of a known concentration react with equal moles of an unknown concentration giving the equivalence point. Also‚ the

protein consists of two sites: a constant region (C) and a variable (V) region. In the constant region‚ the amino acid sequences remain similar to another antigen receptor from another B cell. What determines the main difference in targeting specific types pathogen for each B cell is the variable region. A variable region of an antigen receptor from one B cell has completely different amino acid sequencing than the variable region of another antigen receptor from another B cell. Thus‚ the variable region
