air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before they enter the recycling process. They should only be drained to a purpose built effluent treatment plant so that the acid can be treated and neutralized. Next the batteries are broken in a hammer mill

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

H2SO3 Sulfurous acid is the chemical compound with the formula H2SO3. H2SO3 is a clear‚ colorless liquid with a sulfurous odor. It is a weak acid that is formed when sulfur dioxide is dissolved in water. Sulfurous acid is used as a bleaching and chemical reducing agent that is often used in medicine‚ throat and nasal sprays and skin lotions. Antiseptics‚ anti-fermentative‚ and antizymotics include sulfites that are formed from the acid. This compound is only stable in aqueous solutions‚ and

Chemistry A Rap 1 4/6/12 Acid and Base Report If someone were to ask the common teenager in the US‚ “What’s acid?” they would probably respond with something akin to “It’s that one drug that makes you see stuff that isn’t really there and just kinda makes you crazy”. And if that same someone was to ask that same teenager‚ “What’s a base?” their response would most likely have something to do with either baseball‚ or freeze-tag. The thing is‚ most people don’t really understand the most common

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

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything

Every solution has either has an acid or basic trait. The acid or basic trait in a solution are called pH level. pH is a scale that is used to determine if solution is acidic ‚basic‚ or neutral. During Living Environment class‚ we conducted a experiment that allowed us to measure the pH levels of 3 solutions. We were split into groups and each person had to bring a household solution from around the house. There certain materials that were needed to conduct the experiment .The following

The effect on the pH of Distilled water‚ Potato Solution and Commercial Buffer‚ when Hydrochloric acid (0.1 mol/L) and Sodium Hydroxide (0.1 mol/L) is added Mahima Mandava Mrs. Haist September 23rd‚ 2014 SBI4U1 Background Information: The pH is the measurement of how acidic or how basic a substance can be. The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors

Eichbauer IB Chemistry II – Period 6 16 February 2015 Investigation of the Effects of Acid Rain Background Information Acid rain is when there is a mix of wet and dry deposited material in the atmosphere that have higher levels of nitric and sulfuring acid. These chemicals formed can be from natural causes‚ like volcanoes and the decay of vegetation‚ or man made causes like fossil fuel combustion. Acid rain can be measured using the pH scale‚ and will always be on the lower end of the spectrum
